Ultimate Spinach is the 1968 self-titled debut album by the American psychedelic rock band Ultimate Spinach, and was released on the MGM Records label (E/SE-4518) simultaneously with the debut LP of two other Boston-area bands, Beacon Street Union and Orpheus. Both albums were heavily promoted by the label as being representative of the "Bosstown Sound". The commercial ploy was heavily driven in psychedelic music that attempted to replicate the San Francisco Sound.
