The Tripsichord Music Box was an American psychedelic rock group of the 1960s. They were managed by Matthew Katz, who also worked with Jefferson Airplane, Moby Grape and It's a Beautiful Day. Their loyalty to Katz, at a time when many San Francisco bands were signing recording deals with Los Angeles-based labels, may have contributed to their relatively unknown status today. Led by guitarist and singer/songwriter David Zandonatti, Tripsichord recorded a full-length LP and several singles for Katz's San Francisco Sound label. They were the first San Francisco group to record on 8-track equipment.

Frank Straight (guitar), Tony McGuire (guitar), Oliver McKinney (keyboards) and Randy Guzman (drums), performing as 'The Ban and based in Lompoc, California released one 45 RPM single ("Bye-Bye" / "That I'm Hoping") in 1965 on a small label called Brent records. McGuire was drafted into the military, and circa 1966 Zandonatti joined The Ban, originally as a bassist. They then moved to Los Angeles, signed to Jack Berle's Embassy record label changed their name to The Now, played some Sunset Strip clubs, and released a single on Embassy, "I Want" / "Fly Like a Bird". Soon they moved to San Francisco and signed up to be managed by Matthew Katz, who came up with the name Tripsichord Music Box.
