Josh Homme performed an unreleased song last night at a benefit show for Afghan Whigs guitarist Dave Rosser. Rosser was recently diagnosed with inoperable colon cancer, and fellow musicians are coming together to raise money for his treatment. Homme’s new song is called “Villains Of Circumstance,” and he performed it acoustically for fans at the Teragram Ballroom in LA. Other performers included Eagles Of Death Metal and the Gutter Twins with Duff McKagan. On top of playing a new song, Homme also covered Johnny Cash’s “Dark As A Dungeon,” Cab Calloway’s “Minnie The Moocher,” and Them Crooked Vultures’ “Spinning In Daffodils.” Check out videos of “Villains Of Circumstance” and two of the covers below.
