Ben Harper, Tom Morello and Serj Tankian will perform at a South by Southwest showcase for the documentary and soundtrack "Body of War," inspired by a U.S. soldier paralyzed while serving in Iraq.

The performance is set for March 13 at Stubbs BBQ in Austin, Texas, and will also feature Kimya Dawson, American Bang, Brendan James, RX Bandits and special guests to be announced.

As previously reported, "Body of War" chronicles the experiences of Tomas Young, who also curated the film's accompanying soundtrack, due March via Sire. The first single is Eddie Vedder and Ben Harper's "No More."

"If you?re a fan of a particular kind of music, maybe you pick it up because you like Lupe Fiasco or Public Enemy, and then you get some Ben Harper accidentally thrown into your ear hole that maybe makes you think a little more about a different subject," Young tells Billboard.

"Body of War" will screen at Austin's Paramount Theater just prior to the artist showcase. A nationwide theatrical release begins March 7 in Kansas City, Mo.
