NAT 28 kicks off the summer with a performance of Terry Riley's iconic open-instrumentation piece, In C at the Three Rivers Arts Festival. In C is often cited as the first minimalist composition ever and consists of 53 short, numbered phrases played an indeterminate amount of times by each performer. NAT 28 is proud to pay homage to Terry Riley, an American composer who has inspired so much of the aleatoric music that the ensemble is now known for.
