California Guitar Trio originally met after participating in one of King Crimson legend Robert Fripp’s Guitar Craft Courses. The influence shows. Since their 1991 inception, the Trio has released a dozen albums of technically dazzling six-string soundscapes. But what separates them from other contemporary virtuoso acts is their eclectic vision, integrating prog, classical, psychedelia, even surf rock, into one forward-looking package. Andromeda, their first album of all-original pieces, is their finest yet. Each player — utilizing acoustic, electric and classical guitars — occupies one stereo channel, forming an interlocking funnel of melody and white-hot rhythm. “Cathedral Peak” is a gorgeous, edge-of-your-seat thriller set in 5/4; “Portland Rain” is appropriately titled, with stereo-engulfing acoustics shimmering like pointillistic dots in a gold-plated, classically tinged flash flood. If relentless arpeggiating ain’t your bag, look elsewhere. But if you like your prog informed by craft as much as wizardry, Andromeda is the perfect destination.
