Now in its eighth year, the Austin City Limits festival has worked hard to broaden the city's laid-back, hippies-and-roots-rockers reputation by booking edgier acts like the Pixies, Massive Attack, the Mars Volta, N.E.R.D., and Queens of the Stone Age. For the 2010 incarnation of the ACL Fest, though, they seemed instead to embrace it -- headliners included Phish and the Eagles, respectively, with a Saturday night set from M.I.A. providing one of the few deviations from the rock band-heavy lineup. This worked in the festival's favor, for the most part. The consistency and quality of those chosen bands -- the Strokes, the Flaming Lips, Sonic Youth, Muse, the National, and Band of Horses all performed -- meant that instead of a mishmash of headliners from around the pop spectrum, the cup overflowed for rock fans.
