During the late 80’s and early 90’s, Mark played guitar and keyboards for several bands in the crazy fun, thriving San Francisco Rock Circuit. Playing at legendary clubs like the I-Beam, Nightbreak, Paradise Lounge, Kennel Club, and others, Mark contributed in the bands Galaxy Chamber, Electric Range, Doomsday Cafe, Lip Service, Sonic X, and Aerial Dreams. It was truly a special time in history that couldn’t have been any wilder for band members and audiences alike!
