The album garnered significant attention for its sophisticated sound, particularly highlighted by the hit single 'Holdin’ On to Yesterday,' which reached No. 24 on the Billboard Hot 100. This success helped to solidify Ambrosia's presence in the progressive rock genre and laid the groundwork for their future releases.
