The Cabrillo Festival of Contemporary Music's final day showcases ‘Melt + Sprout,' composer Sean Shepherd's meditation on the catastrophic loss we're all facing due to climate change. ‘Melt' and ‘Sprout' are two separate compositions, the former a heartbreaking lament and the latter it's more hopeful sequel. Illustrated by the work of photographer Camille Seaman, as well as by cutting-edge animation, the twin pieces are presented virtually on-line with music from the Cabrillo Festival Orchestra,followed by a live talk-back and Q&A session with the artists. The event begins at 7 p.m.
