Digitally restored by Pentimenti Productions, Suzanne Simpson's "Karl Wirsum" is a little-known 1973 film that peeks into the sun-dappled California studio of a young artist as he embarks on an extraordinary career. Wirsum's psychedelic marionette sculptures still dazzle today, while his narration and a mind-bending soundtrack draw viewers into his process and personality. Part of "4 Films by Suzanne Simpson," a whimsical quartet of archival films that captures artists flourishing amidst the 1970s Bay Area art scene, when Funk art was thriving.
