During QUEENS OF THE STONE AGE's recent European tour, the band played an exclusive unplugged set one mile underground in a former salt mine in Erfurt. Germany.Open to worldwide competition winners only, the November 20 set saw QOTSA breaking out songs they've never played live (going "deep", in the words of frontman Josh Homme, who is always quick with a pun). Check out photos of concert at this location. A teaser clip featuring some of the underground footage can be viewed below. A longer film documenting the experience is currently being prepared for future release. In other news, QUEENS OF THE STONE AGE will perform on Anthony Bourdain's television program "No Reservations" on December 10 at 10 p.m. ET/PT on the Travel Channel. Josh Homme told Billboard.com in October that he is so happy with QUEENS OF THE STONE AGE's current lineup that he can't wait to get the group back into the studio to work on new material. "The other night we were up 'til six in the morning, all of us playing guitar," Homme said of a roster that includes multi-instrumentalist Troy Van Leeuwen and drummer Joey Castillo, who joined in 2002, and new members bassist Michael Shuman (WIRES ON FIRE) and utility man Dean Fertita (THE RACONTEURS, THE WAXWINGS). "QUEENS sounds better than it ever has live," Homme continued, "but we're trying to figure out how to tour and how to (write and record), 'cause I think for everyone right now the idea of creating something is even more enticing than going on the road. This lineup feels like we could basically blow through a whole record quick."
