It's a Beautiful Day was an American rock band formed in San Francisco in 1967, known for blending rock, jazz, and classical music influences with orchestral arrangements. The group achieved mainstream success with their 1969 hit "White Bird" and their self-titled debut album, which showcased their innovative and eclectic sound. Led by violinist and keyboardist David LaFlamme, the band became emblematic of the San Francisco psychedelic rock scene before disbanding in the mid-1970s.
