SYCH is both an acronym for the dream-team avant jazz quartet of Wally Shoup/C. Spencer Yeh/Chris Corsano/Bill Horist, and the heady, buzzing state of mind achieved while immersed in their glorious fire-ringed soundpools. The players combined resume reads as a borderline hyperbolic whos who of contemporary experimental and improvised music: Shoup is a free jazz veteran from Seattle, WA who leads his Wally Shoup Trio and Project W, and has collaborated with Nels Cline (Wilco etc), Thurston Moore (Sonic Youth etc), and Paul Flaherty; Yeh is most known for leading Burning Star Core and boasts countless live and recorded collaborations in his own right; Corsano is a shining light in avant music, most recently as a member of Rangda (with Sir Richard Bishop and Ben Chasny) and is a tremendously in-demand and diverse percussionist, performing with people that range (literally) from Bjork to Jandek, and on recordings with Six Organs of Admittance, Nels Cline and dozens more; Horist is a West Coast signature guitarist, composer and improviser, with scores of recordings and collaborations alongside such names as Bill Frisell, Eugene Chadbourne, and Steve Fisk. The sum of the individual parts is staggering as displayed on Lunar Roulette, an astonishing album brimming with ecstatic excursions into the outer regions of free music.
