Randy Peterson is best known for his drumming in various contexts with free jazz saxophonist/clarinetist Joe Maneri and his son Mat, a violist. Peterson's style is often rather relaxed and episodic, in that his drum hits come in flurries. It's as if he conceives his playing in terms of sets of phrases with clear beginnings and ends, even though most of his playing is metrically free. Peterson's first high-profile recording was Joe Maneri's Let the Horse Go, recorded in 1993 and released in 1995. Since then he has played on a variety of Maneri recordings, including several Joe Maneri records on the Leo, Hat and ECM labels, and a number of Mat Maneri albums. 2002 also saw the release of the Maneri Ensemble's Going To Church, a sextet album featuring both Joe and Mat along with Peterson on drums. Since the 1990s, Peterson has also appeared live with the Maneris in various contexts. Since 1998, Peterson has appeared alongside bassist Nate McBride on two albums by pianist Pandelis Karayorgis; in 2002, Peterson surfaced on another Karayorgis album, this time with Mat Maneri, saxophonist Tony Malaby and bassist Michael Formanek.
