If Comedy Central is your default TV channel, you know who Bill Burr is. Since his recurring appearances on Chappelle’s Show, Burr has gone on to do a number of televised specials and has become a regular guest on both The Late Show With David Letterman and the Opie And Anthony radio show. He co-hosts his own XM show, Uninformed, with fellow comedian Joe DeRosa, and his most recent TV project was an hour-long special on Comedy Central called Let It Go, which is now available both in stores and via his website. Catch him at the Tower Theatre in Philadelphia on Saturday April 9 and don’t forget to pee before you sit down. Showtime 8 p.m. Tickets $32.50 via LiveNation.
