Emerging from the Bay area underground circa 2001, electro-noise duo Yellow Swans (Pete Swanson and Gabriel Mindel Saloman) draw layers of abstract noise from disjointed drum machine rhythms, guitar feedback and all manner of broken electronics. The result is a weirdly inclusive brand of mangled glitch disco that elevates the listener rather than locking him behind impenetrable walls of noise. Befitting of DIY anarchists with an avowed idealist agenda, the group’s arcs of reverberating pulses open doors to a shared experience, which is meant to serve as a figure for cultural and political Utopia, not mere mindless banging and scraping. The duo plays at Soundlab with Grouper and Post this Sunday (Sept. 24), 9pm.
