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

• HOUR 2: EPFC DJS
