Lis Rhodes' double-projection opus Light Music makes a rare US appearance at this fundraiser for three favorite outfits (Triple Canopy, the Public School, and Light Industry) and their massive new space. The British artist's 1975 classic is an experimental work that capitalizes on the possibilities of 16mm optical sound — in other words, the projector translates the abstract visual into audio. The screening follows a reading by Believer editor Ed Park and author Lynne Tillman, and precedes Ambergris' self-described "Anti-Matter Cabaret." The interdisciplinary evening keeps it going well into Sunday, with sets by pop ensemble Skeletons and several DJs.
