Two artists who packed the upstairs stage at World Cafe Live during the Non-COMMvention back in May will be co-headlining downstairs in September, the venue announced today. At the top of the bill is The Last Bison, who we’re excited to see at the XPoNential Music Festival next week. Equally exciting (possibly moreso) is David Wax Museum, who stole the show at NonCOMM back in May with a unique, lively and crowd-participatory performance. Tickets for the September 14th show go on sale this Friday, July 19th at noon via the World Cafe Live website. Listen to The Last Bison’s Non-COMM set here, listen to David Wax Musuem’s Non-COMM set here, and watch a video of David Wax Museum playing “The Rumors Are True” below.
