Bon Iver will grace the stage at 30 Rock tonight for their debut performance on Saturday Night Live. In a promo video for tonight’s show (which can be seen below), frontman Justin Vernon can be seen sporting a Gayngs T-shirt—the band which features Vernon and a wide array of musicians from groups such as P.O.S, The Rosebuds, Har Mar Superstar, Solid Gold and Megafaun—aside the cast and host Channing Tatum. The group will perform “‘Beth/Rest” and “Holocene” off their GRAMMY-nominated 2011 self-titled album.
