Among creators of video mixtapes—extended montages of found footage assembled around a theme—TV Carnage, just a Canadian guy gifted with unparalleled visual musicality, is without peer. (For proof, see Carnage's 2002 DVD Casual Fridays, the genre's towering masterwork.) Tonight, Mr. Pinky Carnage himself will be in town to introduce his latest mix—the brand-new exercise-obsessed Let's Work It Out!, a shriekingly brilliant assemblage of celebrity workout tapes, noncelebrity workout tapes, and unapologetic shaming of fat folk culled from decades of television.
