L.A. Guitar Quartet: The ecstatically reviewed, blandly named L.A. Guitar Quartet brings new meaning to the phrase "musical chairs": Because William Kanengiser, Scott Tennant, John Dearman, and Andrew York all were accomplished classical soloists before they banded together, each rotates as lead from piece to piece. This is decidedly not the case with most chamber ensembles. But then, L.A. Guitar Quartet is something of a Fab Four on today's classical scene: William is the flashy award winner, Scott the former child prodigy, John the world music aficionado, and Andrew the composer recorded 'round the world. It's enough to make you wanna swoon! The show happens at 8 p.m. at the Morton H. Meyerson Symphony Center, 2301 Flora in the Arts District. Tickets are $12-$54. Call 528-3733.
