(MUSIC) Among string quartets, Kronos is the restless, brilliant teenager. From classical to new music to world music to minimalism, the quartet eats whatever it comes across (and occasionally gets indigestion), but music fans of all loyalties still line up to hear what will happen next. Kronos plays with pop stars—David Bowie, Björk—as well as Texas yodelers, Bollywood singers, Mexican rockers, and tonight, a famous Azerbaijani accordion player. Go. (Moore Theatre, 1932 Second Ave, 292-2787. 8 pm, $32.50—plus $11.31–$36.31 in Ticketmaster fees.)
