Sat.

Thurs. May 28 -- For the last 15 years, I've watched Kamasi Washington mainly as a young saxist with Gerald Wilson, Phil Ranelin, the Pan Afrikan Peoples Arkestra and more, and I've always been impressed with his full-force tenor work. Now, with the release of the three-CD "The Epic," I'm fully forced to be impressed with his boggling chops as a composer and arranger, mature and unignorable. Read my record review here. With Washington's sudden coast-to-coast recognition, reservations may be necessary for this one. 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; $15; 21+; parking $5 underneath off Second Street at the sign of the P in a circle; (213) 620-0908; www.bluewhalemusic.com.

Thurs. May 28 -- The edge-pushing arts organization SASSAS is raising funds by selling "bootleg" album-cover art inspired by old LPs. The many visualizers include music-related names known by non-artists such as me, so let's mention some: Sarajo Frieden (above, flashing on Alice Coltrane), Fredrik Nilsen (remembering the Velvet Underground), Gary Panter (Mothers), Joe Potts (Grateful Dead), Rick Potts (Buddy Colette?), Tom Recchion (Henry Cow), Steve Roden (Fluxus), Eddie Ruscha (Cochin Moon), Michael Uhlenkott (his own Monitor, cheater). It's fun just to check out the selections online and bid until May 31 here. Tonight is the artists' reception at 1301PE, 6150 Wilshire Blvd., L.A. 90048; 6-9pm; free; the covers are viewable here in person May 27-30.
