Terry Riley

Born in Colfax, California in 1935, Riley began performing as a solo pianist during the 1950s. During that decade, he studied composition at San Francisco State University, the San Francisco Conservatory, and University of California, Berkeley, studying with Seymour Shifrin and Robert Erickson. He befriended composer La Monte Young, whose earliest minimalist compositions using sustained tones were an influence; together, Young and Riley performed Riley's improvisatory composition Concert for Two Pianists and Tape Recorders in 1959–60. Riley later became involved in the experimental San Francisco Tape Music Center, working with Morton Subotnick, Steve Reich, Pauline Oliveros, and Ramon Sender. Throughout the 1960s he also traveled frequently in Europe, taking in musical influences and supporting himself by playing in piano bars. He also performed briefly with the Theatre of Eternal Music in New York.

In the 1950s Riley was already working with tape loops, a technology still in its infancy at the time; he would later, with the help of a sound engineer, create what he called a "time-lag accumulator". He has continued manipulating tapes to musical effect, in the studio and in live performances throughout his career. An early tape loop piece titled Music for the Gift (1963) featured the trumpet playing of Chet Baker. It was during Riley's time in Paris, while composing this piece, that he conceived of and created the time-lag accumulator technique. He has composed using just intonation as well as microtones. In New York City in the mid-1960s he played with his longtime friend La Monte Young, as well as with John Cale and tabla player Angus MacLise, who were founding members of The Velvet Underground. Riley is credited as inspiring Cale's keyboard part on Lou Reed's composition "All Tomorrow's Parties", which was sung by German actress Nico and included on the album The Velvet Underground and Nico, recorded in 1966.

His most influential teacher was Pandit Pran Nath (1918–1996), a master of Indian classical voice who also taught La Monte Young, Marian Zazeela, and Michael Harrison. Riley made numerous trips to India over the course of their association to study and accompany him on tabla, tambura, and voice. In 1971 he joined the Mills College faculty to teach Indian classical music. Riley also cites John Cage and "the really great chamber music groups of John Coltrane and Miles Davis, Charles Mingus, Bill Evans, and Gil Evans" as influences on his work. He was awarded an Honorary Doctorate Degree in Music at Chapman University in 2007.

Riley began his long-lasting association with the Kronos Quartet when he met their founder David Harrington while at Mills. Over the course of his career, Riley composed 13 string quartets for the ensemble, in addition to other works. He wrote his first orchestral piece, Jade Palace, in 1991, and has continued to pursue that avenue, with several commissioned orchestral compositions following. He is also currently performing and teaching both as an Indian raga vocalist and as a solo pianist.

Riley continues to perform live, and was part of the All Tomorrow's Parties festival in May 2011.

He has three children: one daughter, Colleen, and two sons, Gyan, who is a guitarist, and Shahn. He was married to Ann Riley until her death in 2015.
