This review by Lindsay Planer is part of the notes alongside the first video:
"Although they are not one of the better-known San Francisco bands to have emerged from the ballroom circuit of the late '60s and early '70s, It's a Beautiful Day were no less memorable for their unique progressive rock style that contrasted well with the Bay Area psychedelic scene. Led by David LaFlamme (flute/violin/vocals) and his wife, Linda LaFlamme (keyboards), the six-piece unit on this album vacillates between light and ethereal pieces such as the lead-off cut, "White Bird," to the heavier, prog rock-influenced "Bombay Calling."
“One of the most distinct characteristics of It's a Beautiful Day is their instrumentation. The prominence of David LaFlamme -- former violin soloist with the Utah Symphony and original member of Dan Hicks & His Hot Licks -- adds a refinement to It's a Beautiful Day's sound. Likewise, the intricate melodies -- mostly composed by the LaFlammes -- are structured around the band's immense virtuosity, a prime example being the exquisitely haunting harpsichord-driven "Girl With No Eyes." It's a Beautiful Day remains as a timepiece and evidence of how sophisticated rock & roll had become in the fertile environs of the San Francisco music scene."
