Every March, thousands upon thousands of inebriated music dorks descend on Austin, Texas for the SXSW Music Festival. The whole idea of the festival is that new acts can make name for themselves by playing umpteen billion shows over five days, but bigger names can also be counted on to make appearances. Headliners like the Shins and Fiona Apple had already announced SXSW shows, and the festival organizers have just added a few more big ones. As Consequence Of Sound reports, the latest round of additions includes Santigold, T.I., Nas, Norah Jones, Jimmy Cliff, GZA, and Cults, as well as SXSW standbys like Curren$y, Freddie Gibbs, Torche, Trash Talk, and Big K.R.I.T. Check the SXSW website for the full list of already-announces shows, and be advised that plenty more will be announced in the leadup to the festival, which goes down 3/13-18.
