It's a Beautiful Day is an American band formed in San Francisco, California, in 1967, featuring vocalist Pattie Santos along with violinist David LaFlamme and his wife, Linda LaFlamme, on keyboards. David LaFlamme, a former soloist with the Utah Symphony Orchestra, had previously been in the band Orkustra, and unusually, played a five-string violin. The other members of It's a Beautiful Day in its early years were Hal Wagenet (guitar), Mitchell Holman (bass) and Val Fuentes (drums). Although they were one of the earliest and most important San Francisco bands to emerge from 1967's social phenomenon Summer of Love, the band never quite achieved the success of contemporaries such as Grateful Dead, Jefferson Airplane and Santana, with whom they had connections. The band created a unique blend of rock, jazz, folk, classical and world beat styles during the initial seven years it was officially together.
