Last night on The Colbert Report, Stephen looked back at the festivities he put together as part of his own festival: StePhest Colbchella ’012 RocktAugustfest. Yeah, that happened. On the bill were the likes of Flaming Lips, Santigold and Grizzly Bear. Last nght on his show he included performance from Grizzly Bear including an interview, a performance of "Yet Again" taken off their forthcoming LP, Shields. As well as that we get to enjoy a rendition of "Sleeping Ute" and "Two Weeks". We expect more footage from StePhest to arrive this week but check out GB's interview at the top with the interviews being available after the jump courtesy of our buddies at The Audio Perv.
