Five composers from Ann Arbor - Robert Ashley, Gordon Mumma, George Cacioppo, Roger Reynolds, and Donald Scavarda - created the ONCE festival because they wanted their music to be heard and they wanted to push the boundaries of contemporary music.
Mark Clague is a music professor at the University of Michigan. He says the 50th anniversary celebration will include lectures, exhibits and concerts – including music from ONCE founder Donald Scarvada.
"One of the things that Don Scavarta does," explains Clague, "is he take the squeaks of the clarinet that you would hear as a mistake, and then he has the clarinets practice those squeaks and learn how to control the squeaks. And so by harnessing what had been an error and then advancing it as a musical event, it really advances the whole notion of what music can be."
That piece is called Matrix for Clarinetists.
Four of the five original ONCE composers will be at the ONCE MORE festival, which runs now through Thursday.
