Terry Riley in 2004
Terrence Mitchell Riley
June 24, 1935
Terrence Mitchell Riley (born June 24, 1935) is an American composer and performing musician   associated with the  minimalist school of Western classical music, of which he was a pioneer. His work is deeply influenced by both jazz and Indian classical music, and has utilized innovative tape music techniques and delay systems. He is best known for works such as his 1964 composition  and 1969 album In C , both considered landmarks of minimalist music. A Rainbow in Curved Air 
Colfax, California in 1935, Riley studied at Shasta College, San Francisco State University, and the San Francisco Conservatory before graduating with an MA in composition at the University of California, Berkeley, studying with Seymour Shifrin and Robert Erickson. He was involved in the experimental San Francisco Tape Music Center, working with Morton Subotnick, Steve Reich, Pauline Oliveros, and Ramon Sender. His most influential teacher, however, was Pandit Pran Nath (1918-1996), a master of Indian classical voice who also taught La Monte Young and Marian Zazeela. Riley made numerous trips to India over the course of their association to study and accompany him on tabla, tambura, and voice. Throughout the 1960s he also traveled frequently in Europe, taking in musical influences and supporting himself by playing in piano bars. In 1971 he joined the Mills College faculty to teach Indian classical music. He was awarded an Honorary Doctorate Degree in Music at Chapman University in 2007.
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, demonstrating how he pulled together strands of Eastern music, the Western avant-garde, and jazz.
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. He is married to Anne Riley. 
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. 
Riley's music is usually based on improvising through a series of
modal figures of different lengths. Works such as (1964) and the In C Keyboard Studies demonstrate this technique. The first performance of In C was given by Steve Reich, Jon Gibson, Pauline Oliveros and Morton Subotnick. Its form was an innovation: The piece consists of 53 separate modules of roughly one measure apiece, each containing a different musical pattern but each, as the title implies, in the key of C. One performer beats a steady pulse of  Cs on the piano to keep tempo. The others, in any number and on any instrument, perform these musical modules following a few loose guidelines, with the different musical modules interlocking in various ways as time goes on.
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 , recorded in 1966.

Riley's famous overdubbed electronic album
(recorded 1968, released 1969) inspired many later developments in electronic music. These include A Rainbow in Curved Air Pete Townshend's organ parts on The Who's " Won't Get Fooled Again" and " Baba O'Riley", the latter named in tribute to Riley as well as to Meher Baba. Charles Hazlewood, in his BBC documentary on Minimalism (Part 1) suggests that the album 'Tubular Bells' by Mike Oldfield was also inspired by Riley's example.  
Riley's collaborators have included the
Rova Saxophone Quartet, Pauline Oliveros, the ARTE Quartett, and, as mentioned, the Kronos Quartet. His 1995 Lisbon Concert recording features him in a solo piano format, improvising on his own works. In the liner notes Riley cites Art Tatum, Bud Powell and Bill Evans as his piano "heroes", illustrating the importance of jazz to his conceptions.
