Jack Black and Kyle Gass phoned into the entertaining NPR quiz show last week to promote their new album, “Rize of the Fenix.”. If you missed the broadcast, check it out on NPR. In traditional (if you can call it that) Tenacious D style, Black and Gass (sounds like a bizarro world version of Arm & Hammer) were hilarious. DDR can’t wait to hear that album. In the meantime, we’d like to see Peter Sagal’s best air guitar performance. His attempt at a falsetto alone would be worth the (high) cost of admission to a live ‘Wait! Wait!’ taping.
