8MM

Described as Massive Attack meets Fleetwood Mac (and, a little more of a stretch, Led Zeppelin at a rave with June and Johnny Cash, though we highly doubt such an incredible sound exists), 8MM is a band that's already gained a following with studio execs—their music has been featured on tons of shows, including Grey's Anatomy, Nip Tuck and Nikita. Hear them live this Halloween and decide for yourself.
