Billy Bragg has joined a growing list of heavy hitters — Ben Harper, Tom Morello, System of a Down's Serj Tankian, and Kimya Dawson, among them — for one of South By Southwest's most anticipated bills. The Austin, TX, music fest's Thursday night lineup will honor the documentary Body of War, about Tomas Young, a 26-year-old Iraq War veteran who was maimed less than a week into his first tour of duty.

The story inspired many of the artists to donate tracks (mostly protest songs) for the Sire Records release, with all proceeds going to Iraq Veterans Against the War. The award-winning doc by Phil Donahue and Ellen Spiro will have its Austin premiere on March 13, preceding the concert at Stubb's BBQ. Although Eddie Vedder, who wrote the anthemic "No More" after meeting Young, is not scheduled to appear, Morello tells EW.com, "I've been trying to lure some more performers." Stay tuned for more artist announcements as we get them.
