California Guitar Trio.

This trio of guitar virtuosos first got together as members of Robert Fripp’s League of Crafty Guitarists and struck out on their own in 1991, when they began playing in California clubs and coffeehouses. Known for its stunning virtuosity and sly sense of humor, the trio plays a brand of progressive acoustic music that fuses classical, jazz, blues, country, rock, and even surf styles. In addition to several originals, its repertoire ranges from an adaptation of a Bach lute prelude and a virtuoso cover of Queen’s “Bohemian Rhapsody” to a medley of the western standard “Ghost Riders in the Sky” and the Doors’ “Riders on the Storm.” Tonight they are joined by NYC guitarist Kaki King. $30.
