The South By Southwest line-up is in, and it is predictably massive. Among the marquee names playing the Austin arts festival are R.E.M., My Morning Jacket, N.E.R.D., Ice Cube, the Raveonettesand Kevin Shields (sans My Bloody Valentine). The four day event will also showcase a bunch of Rolling Stone favorites (Kate Walsh, Black Mountain, Bodies of Water, Holy Fuck, Santogold, MGMT, Ingrid Michaelson. White Denim) and a couple of our Best Bands on Myspace winners (Airborne Toxic Event, the Voom Blooms.) There are also twenty bands that begin with the word "Black," a group from Uzbekistan (Navruz), a band named after Wayne's World's Tia Carrera and eighties pop group Was (Not Was). Rock Daily will be on the scene from March 12-16, reporting on the best shows, best parties and pictures from the festival.
