Bad Radio is a secret archive of shows devoted to a society of 20th century avant-garde musicians and their influences. The fifth installment looks at Terry Riley. From 1962-1964 Riley toured Europe, participating in “happenings,” street theater and jazz concerts. Terry Riley's music has influenced a wide range of musical genres, including rock, pop, dance/trance, and experimental music, as well as 20th and 21st century concert music. His most influential piece is "In C," written in 1964 and first performed by Steve Reich, Jon Gibsom, Pauline Oliveros and Morton Sobotnick.
