Cup is an often-fascinating collaboration between Cibo Matto keyboardist Yuka C. Honda and her guitarist-husband, Nels Cline. A typically atypical performance might involve multi-instrumentalist Honda setting up a labyrinth of starry synth patterns as guitarist Cline manipulates his pedals and responds with looping, dizzying riffs that morph from art-funk into cathartic bursts of pure noise. Shape-shifting instrumental sound effects collide with one another, giving birth to new galaxies of new-music experimentation and improvised psychedelic strangeness. Cline is a longtime local free-jazz iconoclast who has gained wider attention with Wilco, while Honda has done a lot of everything in her extensive career, working as a composer, collaborator and producer with such disparate forces as Beastie Boys, Mike Watt, Tricky, Luscious Jackson and Marc Ribot. Best Coast’s Bobb Bruno also demonstrates his more exploratory, avant-garde side.
