HOMETOWN: Nashville via Chicago

WHY SHE MATTERS: The 28-year-old born Tristen Gaspadarek is one of the most talented new songwriters in a city full of talented new songwriters. Her addictive debut album, Charlatans at the Garden Gate, is making a splash with its impassioned lyrics and hooky guitar pop that blends country, rockabilly, rock'n'roll, girl group sounds, and introspective balladry -- the result of Tristen's expansive study of pop music. And, just like the LP, her live shows -- with a backing band called the Ringers -- are rollicking and sharp.

YOU SHOULD KNOW: When she's not on the road, Tristen works at Nashville's bar and grill the 12 South Taproom, where she serves local musicians like the Kings of Leon. "They're good tippers," she tells SPIN.

LISTEN: Tristen, "Baby Drugs"



HOMETOWN: Hassake, Syria

WHY THEY MATTER: Souleyman is a bonafide legend in his homeland of Syria thanks to his groundbreaking mixture of old world Arabian folk with modernized techno and dance beats — picture Buraka Som Sistema remixing M.I.A. and you're about halfway to capturing his dense, dizzying sound. Souleyman's festival slot is one of only two American dates he has scheduled this year.

YOU SHOULD KNOW: Björk is a huge fan of Souleyman's music and the two have collaborated on a still-untitled single, which is set to be released later this year.



HOMETOWN: Savannah, Georgia

WHY THEY MATTER: Metal is typically underrepresented at Bonnaroo, but Kylesa can easily rep for the genre: The Savannah, Georgia, quintet work up a thunderous doom-and-gloom stoner sludge, flecked with mellifluous melodies and riffs that owe to '60s greats like Jimi Hendrix.

YOU SHOULD KNOW: Kylesa took their name from the Buddhist term Klesa, which refers to a temporary clouding of the mind that results in spastic, unskilled actions. In other words, a perfect summation of their sound — except for the "unskilled" part.

LISTEN: Kylesa, "Don't Look Back"




WHY HE MATTERS: The presence of Eminem on the Bonnaroo bill represents one of the festival's boldest moves into the mainstream in its 10-year history. (He's the best-selling artist in the world over that same period.) Last year's Recovery wasn't his best album, but it was his most revealing, an uneven but mesmerizing exploration of his darkest demons.

YOU SHOULD KNOW: Recovery deals in part with Eminem's return from an addiction to methadone and pain killers, and he found inspiration from an unlikely mentor: Elton John, with whom he famously collaborated on the 2001 Grammys. "Elton John calls me once a week," the rapper told SPIN. "He used to tell me stuff like, 'You're going to start seeing things you've been overlooking.' And it came true."



HOMETOWN: Providence, Rhode Island

WHY THEY MATTER: This four-piece, boasting the wobbly and nicotine-weathered vocals of frontman John McCauley, are one of the most innovative bands in the folk and Americana revival. Part Nirvana, part Hank Williams, they play the dark ballads of their latest album, 2010's The Black Dirt Sessions, with punk gusto and emotional ache.

YOU SHOULD KNOW: The group's love of Nirvana is showing itself this spring and summer when Deer Tick play select sets of Nirvana covers under the name "Deervana."

LISTEN: Deer Tick, "Twenty Miles"



HOMETOWN: Nashville via Butcher Hollow, Kentucky

WHY SHE MATTERS: This coal miner's daughter long-ago rose to the title of "The First Lady of Country Music" by helping to give women a voice in the male-dominated genre. Many of her 16 No. 1 singles addressed women's issues, including birth control, equal rights, and infidelity. At 79, Lynn is enjoying a second — or maybe third — act in her musical career; Jack White produced and played on her last album, 2004's Grammy-winning Van Lear Rose.

YOU SHOULD KNOW: Paramore and the White Stripes contributed songs to a Loretta Lynn tribute covers album, called Coal Miner's Daughter: A Tribute to Loretta Lynn.



HOMETOWN: Nashville

WHY THEY MATTER: This duo of real-life brothers plays sludgy but supercharged rock'n'roll that ranges from Weezer-style, slacker rock to extended-play, Dinosaur Jr.-esque jams. These guys -- who were also featured in our SXSW guide -- seem incapable of playing a show that everyone's not gushing about the next morning.

YOU SHOULD KNOW: The sons of veteran Nashville songwriter Robert Ellis Orrall, Jake and Jamin Orrall started out in Music City's once-buzzed about, now defunct act Be Your Own Pet, which also spawned the careers of Jemina Pearl and Turbo Fruits.

LISTEN: JEFF the Brotherhood, "Shredder"



HOMETOWN: All over

WHY IT MATTERS: As frontman of Gogol Bordello, Eugene Hütz has delivered one small slice of the global music scene -- in his case, the gypsy-influenced sounds of the Ukraine -- to a mass audience. This year, Bonnaroo invited the abundantly mustachioed Hütz to curate his own stage, and he's brought a host of like-minded bands for a big, all-day party in the festival's Other Tent on Saturday.

YOU SHOULD KNOW: Syrian beatsmith Omar Souleyman is among our favorites on Eugene's stage, and we think Bonnaroo fans will get a big kick out of Jovanotti, the Italian rapper who's dominated his home country's charts for a decade.

LISTEN: Gogol Bordello, "Trans-Continental Hustle"



HOMETOWN: New York City via Nashville

WHY HE MATTERS: 29-year-old Justin Townes Earle, son of cult country-folk renegade Steve Earle, is putting a fresh spin on one of the most-recognizable surnames in music, and doing it with a nod to his Americana roots. His latest album, the consistently charming Harlem River Blues, proves he inherited both his father's outlaw spirit and talent for catching his hard-won tears in simple song.

YOU SHOULD KNOW: Steve told Justin to write about what he knew, so the younger Earle dug into his time as a homeless drug user on the streets of Nashville for inspiration on Harlem River Blues.

LISTEN: Justin Townes Earle, "Harlem River Blues"




WHY THEY MATTER: Florence + the Machine have been touring nonstop behind their breakout debut Lungs since 2009, but Brit frontwoman Florence Welch should finally debut new music at Bonnaroo from the upcoming second album, which they're recording at Abbey Road with Bloc Party producer Paul Epworth. Expect some of the new songs to take on a darker edge: Welch said recently she's been writing lyrics that deal with death, dreams, and her recently departed grandmother.

YOU SHOULD KNOW: In an age of when celebrities are constantly Facebooking and tweeting, Welch still likes to maintain a bit of mystery. "I can only manage about one tweet a month," she said recently. "It is just that when I am in a situation where I am doing something amazing it is a shame — rather rude — to bring out my phone and start tweeting."

LISTEN: Florence + the Machine, "Cosmic Love (Short Club Remix)"



HOMETOWN: Los Angeles

WHY THEY MATTER: Daniel Lanois' silky production work has shaped some of rock'n'roll's finest efforts, among them U2's Achtung Baby, and classics by Peter Gabriel, Neil Young, and Bob Dylan. With Black Dub, Lanois created one of his most compelling works as a recording artist, playing piano and guitar in a dub-influenced but supremely bluesy quartet. And since their self-titled debut disc was recorded live in the studio, the music transfers seamlessly to the stage.

YOU SHOULD KNOW: Black Dub is rounded out by the Louisiana-bred rhythm section of bassist Daryl Johnson and drummer Brian Blade, and vocalist Trixie Whitley, whose late father, Chris, was a revered bluesman -- and a pal of Lanois.

LISTEN: Black Dub, "Last Time"



HOMETOWN: Los Angeles

WHY THEY MATTER: While only active for a brief period — from '66-'68 — this Topanga Canyon band helped alter the course of rock'n'roll, as their semi-psychedelic sound and political bent nudged pop music into the counterculture era. Their best-known song, "For What It's Worth," is an authority-questioning Flower Power anthem, and the band's members -- Neil Young, Stephen Stills, Dewey Martin, Bruce Palmer, Richie Furay, Jim Messina -- went on to even greater heights in their subsequent endeavors, from CSNY to Poco to Loggins & Messina.

YOU SHOULD KNOW: They reunited for their first live gig in 42 years last October at Young's Bridge School Benefit, and Buffalo Springfield's Bonnaroo appearance is their sole scheduled date in 2011.



HOMETOWN: New Orleans

WHY THEY MATTER: Wayne's Tha Carter IV is the most anticipated hip-hop release of the year, and with the album tentatively due two weeks after Bonnaroo, expect the rapper to bust out new tracks in his headlining set, which will be beefed up with his hot live band.

YOU SHOULD KNOW: Wayne's new album could shape up to be his craziest-sounding yet: Early tracks have sampled everything from Harry Belafonte's "Day-O (The Banana Boat Song)" to "30 Minutes," from faux-lesbian Russian pop duo t.A.T.u.



HOMETOWN: Chapin, South Carolina

WHY THEY MATTER: On his latest album Kiss Each Other Clean, 36-year-old singer-songwriter Sam Beam "explodes his palette," we said in our nine-out-of-10 review, transforming from a "spare, black-and-white acoustic sketch artist to full-color aural panoramist." The whispering troubadour steps out with a full band with synths, saxophones, gospel and doo-wop sounds, '70s grooves, and even DJ scratches -- and he does it tastefully.

YOU SHOULD KNOW: Before he was a famous musician penning songs like the ones used on soundtracks for the Twilight series, Beam was a professor of film and cinematography at the University of Miami in Florida.



HOMETOWN: Nashville

WHY THEY MATTER: Along with upstarts like Low Anthem, Fleet Foxes, and Those Darlins, Washburn has helped reinvigorate old-timey, roots music. Her stunning new album City of Refuge is a collection of breezy tunes that feature Washburn's intoxicating, nicotine-stained voice and fierce clawhammer banjo-pickin' skills.

YOU SHOULD KNOW: Washburn, who is married to banjo icon Bela Fleck, may be an Americana artist, but she has a deep interest in global sounds: She honed her five-string skills while living in China, where she learned to play Asian folk songs on the instrument.

LISTEN: Abigail Washburn, "Burn Thru"



HOMETOWN: Champaign, Illinois

WHY SHE MATTERS: Krauss is more than just your mom's favorite singer-songwriter — she's a bonafide bluegrass icon who started her career at 12, has been praised by legends like Dolly Parton, and inspired a generation of "newgrass" artists, including Nickel Creek. Her top-notch band includes dobro great Jerry Douglas and Dan Tyminski, whose music was featured in the George Clooney movie Oh Brother, Where Art Thou?

YOU SHOULD KNOW: In 2007, Krauss teamed up with Led Zeppelin's Robert Plant for the Grammy-winning album Raising Sand, and the pair played the Tennessee fest the following year. Since Plant is also at Bonnaroo this year with Band of Joy, keep your fingers crossed for the pair's on-stage reunion.

LISTEN: Alison Krauss, "Lie Awake"




WHY THEY MATTER: America grew up on the late Jim Henson's creations -- the characters of Sesame Street and The Muppets -- from Kermit the Frog to Oscar the Grouch. Now, Henson's son Brian has founded Henson Alternative, and crafted an adult-themed offshoot that honors his dad's edgy roots, which included work for Saturday Night Live.

YOU SHOULD KNOW: At Bonnaroo, the troupe's performance will be two-fold: Fans will be able to watch the movements of the puppeteers onstage, but there will also be a projection of the performance onscreen, as if it were an old-school style Jim Henson TV show.

WATCH: 'Stuffed and Unstrung' clip



HOMETOWN: Louisville, Kentucky

WHY THEY MATTER: Having already played at Bonnaroo five times, the experimental Southern rockers have become the closest thing to the festival's house band. Their four-hour-plus sets are legendary: In 2008, the quintet rocked out during a torrential downpour, offering covers of Velvet Underground, James Brown, Kool and the Gang, Bobby Womack, and Motley Crue to thousands of fans dancing in the mud.

YOU SHOULD KNOW: MMJ recorded their excellent back-to-basics new album Circuital in the gymnasium of an old church outside their hometown.

LISTEN: My Morning Jacket, "Circuital"

21. J. COLE


HOMETOWN: Fayetteville, North Carolina

WHY HE MATTERS: The North Carolina-based rapper was the first to be scooped up by Jay-Z for his budding Roc Nation empire and, after releasing a pair of well-received underground mixtapes, Cole has added his signature voice (a laid-back Southern drawl that occasionally perks into a Kanye-style frenzy) and clever gift for wordplay to tracks by Wale and Talib Kweli.

YOU SHOULD KNOW: Cole toiled as a bill collector before he was summoned by Jay-Z to New York. Needless to say, Cole was ready to call it quits immediately: "I didn't even ask questions. I just left straight out of the job," he said.



HOMETOWN: Austin, Texas

WHY THEY MATTER: The instrumental rockers' career is reaching a high-water mark this year after the release of their lilting sixth studio album, Take Care, Take Care, Take Care, which debuted at No. 16 on the Billboard 200, and their April headlining gig at Radio City Music Hall. Sunday at dusk will be an ideal hour to absorb their heady soundscapes.

YOU SHOULD KNOW: The band's reach has broadened by the appearance of their music in both the film and TV series of Friday Night Lights, which chronicles the high-pressure world of Texas high school football. But the TV show's theme song, often attributed to EITS, is actually by the show's musical director, W.G. Snuffy Walden.

LISTEN: Explosions in the Sky, "Trembling Hands"

23. DR. JOHN


HOMETOWN: New Orleans

WHY HE MATTERS: The treasured pianist and singer is doing double duty at Bonnaroo, playing two very different sets. On Saturday night, the Doctor will team with Big Easy mainstays Allen Toussaint and the Meters to perform his 1974 album Desitively Bonnaroo, which inspired the festival's moniker. Then on Sunday he'll join Black Keys singer-guitarist Dan Auerbach for Superjam, Bonnaroo's annual freeform, guest-filled extravaganza.

YOU SHOULD KNOW: Dr. John, who was inducted into the Rock and Roll Hall of Fame this year, began his career as a backing musician, playing under his real name, Mac Rebennack, behind the ivories for late-'60s pop stars Sonny & Cher and as a session player for superstar producer Phil Spector.



HOMETOWN: Cincinnati, Ohio

WHY THEY MATTER: With so much scouting done online these days, it's rare to see a live industry freakout happen over a new band. But when this poppy, art-rock quartet opened for Panic! at the Disco earlier this year in New York City, potential managers and booking agents jockeyed to meet them. And while they remain unsigned to a record deal, appearances at Bonnaroo and Lollapalooza are on tap this year, plus dates supporting Weezer and Grouplove.

YOU SHOULD KNOW: Nicholas Petricca, the band's mastermind, originally started Walk the Moon as a student at Kenyon University, and their breakthrough single, "Anna Sun," is named after a favorite professor from the school.

LISTEN: Walk the Moon, "Lisa Baby"



HOMETOWN: Birmingham, England

WHY THEY MATTER: Because Led Zepplin's Robert Plant is one rock'n'roll's greatest frontmen. Even at 62.

YOU SHOULD KNOW: His current line-up for Band of Joy — the ever-evolving group founded by Plant in the '60s — features a Murderers' Row of roots-rock musicians, including singer Patty Griffin, guitarist Buddy Miller, drummer Marco Giovino, and multi-instrumentalist Darrell Scott.

LISTEN: Robert Plant & Band of Joy, "Angel Dance"




WHY HE MATTERS: A session guitarist who made his name recording with late '50/early '60s Motown groups like the Isley Brothers, the Supremes, and the Temptations, Coffey is an influential axeman who introduced the wah-wah guitar sound to the top of the charts. Also a producer and film scorer, his 1971 instrumental single "Scorpio" sold millions and has been sampled by LL Cool J, Moby, House of Pain, Public Enemy, and Girl Talk, among others.

YOU SHOULD KNOW: Dennis Coffey, his new album, features contemporary artists -- including Mayer Hawthorne, members of the Dirtbombs and the Detroit Cobras, and Paolo Nutini -- singing over new renditions of classics Coffey originally played on, from acts like Parliament and Wilson Pickett.

LISTEN: Dennis Coffey, "All Your Goodies Are Gone" (feat. Mayer Hawthorne)




WHY HE MATTERS: When the 27-year-old New York University grad (dramatic writing, class of '06) isn't starring on NBC's Community or doing standup on Comedy Central, or acting in his internet sketch troupe Derrick Comedy, he's recording and performing under his rapping guise Childish Gambino. Talk about multi-talented. His rap career took off with the release of this spring's EP, boasting the standout track "Freaks and Geeks," and his spring tour — a combo of comedy and music — is a hit, selling out shows in just hours. Glover is currently working on his next LP, due this fall.

YOU SHOULD KNOW: Glover got his musical moniker by running his birth name through the Wu-Tang Clan name generator.

LISTEN: Childish Gambino, "Freaks and Geeks"
