British rock quartet Editors are back with a new album -- and something is missing, glaringly so: guitars.

Portland, OR, foursome Hockey recently dropped by SPIN's Manhattan offices for a rooftop set of tunes from their debut album, Mind Chaos.

Thursday, MTV's European Music Awards took place in Berlin, Germany, 20 years after the fall of the Berlin Wall. U2, Jay-Z, Katy Perry, Shakira, and others performed -- and Beyonce walked away with three trophies, the night's biggest winner. Check out our take on the event's best & worst moments:

At the Pixies' Hollywood Palladium show on Wednesday night, the sold-out crowd of 4,000 seemed caught between genuflecting respectfully and just going nuts. Kicking off a 21-date U.S.

It's a busy week in the ongoing saga of Chris Brown and Rihanna.

Here are some of the weirdest stories we've seen on the web this week:

Weezer have come a long way from destroying sweaters. Check out the Weezer Snuggie! [YouTube]

Tuesday night at Michigan State University, angsty rock fans with angular haircuts and all-black wardrobes stood alongside preppy Greek Row members to watch Taking Back Sunday and the All-American Rejects -- reps from the introspective and fun-lovin' poles of the emo genre, respectively -- kick off their joint U.S. tour.

Music supervisor for hit TV shows including Gossip Girl, Grey's Anatomy, and Mad Men -- along with the Twilight movie series -- Alexandra Patsavas has quietly made herself one of the most influential figures in the industry, helping to break new bands and shape the aesthetics of popular drama.

When he's not commandeering the stage as the boisterous bassist for SoCal punks Blink-182, Tweeting wisdom to more than 1.4 million followers, or handling album production duties for bands like Motion City Soundtrack and New Found Glory, you'd think Mark Hoppus would turn down the music.

One of the best live sets we saw this summer was by Los Angeles hip-hop duo People Under the Stairs, whose energy transformed a muddy Bonnaroo Day into a wild house party with jumping bass and MCs Thes One and Double K's dope rhymes about -- what else? -- smoking weed and drinking booze!

Some things get better with age: wine, violins, Devo. Unlike other vintage rock acts, the Akron, Ohio New Wave satirists deserve their place on that particular short list. That much was made clear to the packed house at Hollywood's Henry Fonda Theater, who were there to witness the opening salvo of Devo's new tour.

The music video for Rihanna's new Rated R (out Nov. 23) track "Wait Your Turn" has hit the web, and like the song itself, the black-and-white clip is, well, total snoreville.
