God is a concept, people. John Lennon said it, it must be true. Wilco frontman Jeff Tweedy apparently agrees. Last week, Tweedy took the stage with the Autumn Defense, a band that features Wilco members, to perform Lennon's absolutely inimitable Plastic Ono Band track "God," in tribute to the 30th anniversary of Lennon's passing. It's a pretty pitch perfect take, and features a very intense, provocative vocal performance from Tweedy. Check out the video above. [24Bit]
