California Guitar Trio (CGT) is a band of three guitar players founded in 1991. The three—Paul Richards of Salt Lake City, Utah, Bert Lams of Affligem, Belgium, and Hideyo Moriya of Tokyo, Japan—met at a 1987 Guitar Craft course, in which Robert Fripp instructed them in the New Standard Tuning (NST). After completing several of Fripp's Guitar Craft courses, the three toured as part of Robert Fripp and The League of Crafty Guitarists.

Continuing their collaboration then in Los Angeles, they founded The California Guitar Trio in 1991. They continue to play in the New Standard Tuning. Their performances and recordings include original compositions, surf covers, and classical re-workings of classical music. Their influences include European classical music, rock, blues, jazz, world music, and surf music. California Guitar Trio emphasizes technical virtuosity and displays humor.
