Optical Track is a weekly show presented by members of the Echo Park Film Center Co-op, a group of artists who collectively staff EPFC as volunteers for the cinematic revolution. Each week features a sonic slideshow as we turn off the projector bulbs and turn up the sound.

Every second Tuesday of the month, EPFC brings listeners:

• HOUR 1: Lisa Marr & Friends

• Conversation and music with Anne Maureen McKeating, director of the Larry Spring Museum in Fort Bragg, California

• HOUR 2: EPFC DJS

• What Is The Best Chocolate Chip Cookie in Los Angeles? and other existential questions
