Evidence

Reich served as sound engineer and premiered his twelve-minute phased tape-loop Come Out, a visceral, hypnotic, percussive piece based on countless repetitions of a phrase used by one of the Six about having to demonstrate against police brutality by making the “bruise blood come out to show them.” — J. Hoberman, Everything Is Now, 1041
