Kids: all they wanna do is shred. Say you bought your teenager a Stratocaster last year, and every day you have to hear Cradle of Filth songs emanating from the amp in the bedroom. No dis to Cradle of Filth or anything, ’cause you’re a hip parent and all, but you’re dying to introduce a different type of music to the neverending barrage of Boss Distortion pedals. Try then, if you will, John Pizzarelli. The jazz guitarist shreds the hell out of songs like “Avalon” and “I Got Rhythm” with the kind of speed and dexterity that would inspire even the crustiest metal diehard, and he plays Friday, March 11, at the Napa Valley Opera House. 1030 Main St., Napa. 8pm. $40–$45. 707.226.7372.
