Quite possibly Contemporary Art Month’s wackiest offering, “Pretty Plastic” celebrates two decades of the ever-playful, retro-futuristic stylings of Hyperbubble — a local synthpop act comprised of married couple Jess and Jeff DeCuir. Art scene fixtures who’ve performed at Luminaria, the McNay, SAMA and Blue Star, Jess (vocals, theremin, keyboards) and Jeff (vocals, synthesizers, sequencers) have made names for themselves abroad by touring and recording in England, Scotland, France, Germany, Italy and Japan. “A multimedia retrospective” complete with live performances, videos, photographs, costumes, posters and album art, “Pretty Plastic” borrows its name from a forthcoming compilation packed with songs such as “Synesthesia” (a love song to their synthesizers), “Non Biodegradable Hazardous Waste Disposal” (a track inspired by the Patriot Act) and 20 other oddities that run the gamut from dubs and remixes to obscure TV show soundtracks. Hosted by K23, the evening kicks off with a performance by “visionary space cowboy” Garrett T. Capps (9pm) and will be recorded live by Chicago-based filmmaker Joe Wallace for his upcoming project Cowgirls and Synthesizers. $5, 7-11:30pm Sat, Mar.
