Meet two of the most famous guys from Madison you may have never heard of. Eddie Guerriero is a rare book dealer. Mitchell Deprey is a social worker-turned-insurance salesman. But 20 years ago – and again today, thanks to a documentary film that premiered at the 2011 Sundance Film Festival and shows next weekend both in Madison and at New York?s Museum of Modern Art – the duo unwittingly created an underground audio sensation. What they recorded with their microphone launched a creative explosion and, in the words of one fan, can “burn the hair off your ears.” The pair are UW-Madison alumni.
