Fri.-Sun. Aug. 24-26 -- Christian McBride could surprise you with all kinds of electro shenanigans or (more likely) stick to his more trad stuff, but either way you're gonna hear some of the best bass playing around when he leads this trio.

Mon. Aug. 27 -- Temperate/intemperate California pianist Josh Nelson dedicates tonight to a conceptual suite (with visuals from Video Traveler) related to the Mars Rovers. With trumpeter John Daversa, guitarist Larry Koonse, bassist Dave Robaire and drummer Dan Schnelle.

Wed. Aug. 29 -- Bucking my principled opposition to the insidious notion of "Celebrating Peace," I have to recommend this show on the strength of the musicians: Herbie Hancock, Wayne Shorter, Dave Holland and Marcus Miller (Miles Davis vets all), plus hot drummer Cindy Blackman Santana (elsewhere check out Spectrum Road, her crazy Tony Williams project with Jack Bruce, John Medeski & Vernon Reid), Blackman's annoying old man, and a bunch more top players. They better not wimp out just cuz of the theme; if you wants peace you gots to be tough. At the Hollywood Bowl, 2301 Highland Ave., Hollywood 90068; remaining tix $24-$114; (323) 850-2000; www.hollywoodbowl.com.

Thurs. Aug. 30 -- Everybody's raving about the rhythmic/harmonic omniculturality of pianist Vardan Ovsepian; scrutinize him unmercifully in this solo set. At the Blue Whale on the third level of Weller Court Plaza, south of East First Street between South Los Angeles Street and South San Pedro Street, Little Tokyo 90012; 9pm-midnight; $10; parking $5 underneath off Second Street at the sign of the P in a circle; (213) 620-0908; www.bluewhalemusic.com.
