It's a Beautiful Day was a band formed on a beautiful day in San Francisco in 1967, and was the brainchild of violinist and vocalist David LaFlamme. David has been in a band called Orkustra with Bobby Beausoleil. The other members were David's wife Linda (keyboards), Pattie Santos (vocals), Hal Wagenet (guitar), Mitchell Holman (bass) and Val Fuentes (drums). Their debut album, the self-titled It's a Beautiful Day, was released in 1969. They were a bit of a latecomer in the psychedelic scene...
