The Turtle Island Quartet is a string quartet that plays hybrids of jazz, classical, and rock music. The group was formed in 1985 by David Balakrishnan, Darol Anger, and Mark Summer in San Francisco. They released their first album on Windham Hill Records in 1988 with Irene Sazer.

The group plays jazz standards and original compositions that cross several styles, including blues, classical, jazz, and world music. Violinist David Balakrishnan got the idea for a jazz string quartet in 1985. He invited cellist Mark Summer, who had been working for three years as a member of a Canadian orchestra. One of the first pieces they played was Balakrishnan's arrangement of "Stolen Moments" by Oliver Nelson which was released on their first album in 1987. The group's members have included violinist Evan Price and Danish violist Mads Tolling.

As a child, Balakrishnan was inspired by Jimi Hendrix. Then he discovered jazz and the music of the David Grisman Quartet.

Balakrishnan's arrangement of "A Night in Tunisia" by Dizzy Gillespie was nominated for an Grammy Award. The group won a Grammy Award for its version of A Love Supreme by John Coltrane.

The quartet has worked with Paquito D'Rivera, Ying Quartet, Edgar Meyer, the Manhattan Transfer, Modern Jazz Quartet, and the Detroit Symphony Orchestra. Wikipedia
