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. Techniques Riley's music is usually based on improvising through a series of modal figures of different lengths. Works such as In C (1964) and the Keyboard Studies (1964–1966) 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
