The members of California Guitar Trio first got together as students of King Crimson guitarist Robert Fripp, and went on tour with Fripp’s League of Crafty Guitarists in the late 1980s. And while Paul Richards, Bert Lams and Hideyo Moriya display impeccable credentials as all-purpose eclectics — a typical set list will feature original compositions along with versions of “Classical Gas” and “Bohemian Rhapsody” — the trio specializes in a classical-rock fusion that sounds like New Age music with teeth. On such tracks as “Melrose Avenue,” they fashion a dense, propulsive style that incorporated elements of Arabic music, not to mention a sly sense of humor. Last year’s excellent Andromeda sported original tunes that combined lyricism with rhythmic thrust — if “Improv IX” was gorgeous and laid-back, “Hazardous Z” made it clear these guys aren’t interested in producing sonic wallpaper. Like Fripp himself, they’re expanding the guitar vocabulary in fascinating ways.
