Bay Area experimental music and sound collage band Negativland was a favorite curiosity of mine in School. They released the U2 EP in 1991 and immediately upon its release the band was sued by Island Records, U2's record label, for its misleading artwork and use of unauthorized sampling.
The songs on the record parodied the 1987 hit "I Still Haven't Found What I'm Looking For", and today's track features musical backing to a now infamous and profane rant from Casey Kasem. The story goes that he lost his composure during a frustrating rehearsal and the raw feed had gone out to many stations, whose engineers taped and circulated it.
