ANANSI
Earshot Jazz kicks off a new season of their Voice & Vision series with Anansi, a quartet led by trumpeter Jim Knodle. Named for the trickster spider of West African folklore, Anansi wends it way through standards, extended improvisations, and occasional oddities like a hymn setting by Vincent Persichetti. Seattle Asian Art Museum, Volunteer Park, 547-6763, 7 pm, $7.
BILL HORIST
After a recent scorching performance with William Hooker and a probing trio set at the Improv Fest, Bill Horist is on a roll. This eminent practitioner of the prepared guitar plays two sets: one with layers and layers of loops, the other focusing on more fractured improvisation. Polestar Music Gallery, 1412 18th Ave (at E Union), 329-4224, 8 pm, $6.
MIKE BISIO
Bisio, an in-demand jazz bassist, serves up a rare solo show. His ferocious, meditative, and tender playing is not to be missed. Polestar Music Gallery, 1412 18th Ave, 329-4224, 8 pm, $6.
NORTHWEST MAHLER FESTIVAL
Conductor Geoffrey Simon leads the Northwest Mahler Festival Orchestra and Chorus in the Seattle premiere of Gustav Mahler's cantata Das klagende Lied. Also on the bill: William Walton's Portsmouth Point Overture, and perhaps the best entryway into Mahler's massive symphonies, the comparatively slender Symphony No. 4 in G Major. Meany Theater, UW campus, 800-965-4827, 3 pm, $15/$12.
SEATTLE CHAMBER MUSIC FESTIVAL
This gig has a nice mix of hits and rarities, including essentials by Bach, Mozart, Beethoven, and Chopin along with string quartets by the young Tchaikovsky and Joaquín Turina. Lakeside School, 14050 First Ave NE, 283-8808, 7 pm, $15-$32.
FRANK JUNK/TROY SWANSON
Known mainly for his electronic work with experimental ensemble Utterance Tongue, Frank Junk also builds thumb pianos and musical instruments made of springs and wires. Trimpin associate and instrument builder Troy Swanson performs on an appealing contraption dubbed the "corpus callosum." Coffee Messiah, 1554 E Olive Way, 861-8233, 8 pm, free.
DIGITAL FUSIONS
A fixture of the UW Summer Arts Festival, this concert blends electroacoustic music, digital video, computer animation, and live performance in glorious surround sound. Open (and free) rehearsal at 2:00 p.m. Meany Theater, UW Campus, 543-4880, 7:30 pm, $10/$8.
YES
Back in the '70s, Yes, along with Genesis, ELP, King Crimson, and lesser-known prog outfits like Gentle Giant, egg, and Henry Cow burst the barrier between classical and rock. While some of those epic guitar solos, obtuse titles, and excessive stage paraphernalia (colossal mushrooms, impressive tiers of orchestral musicians, and more lasers than the Death Star sequence in Star Wars) are best forgotten, the prog-rockers did more to push the boundaries of rock than anyone else, before or since. Paramount Theatre, 911 Pine St, 628-0888, 8 pm, $41.50-$127.
