The 31st of February made an obscure album for Vanguard in the late 1960s that was typical of many LPs of the time that didn't make an impression.
There was a little bit of folk-rock, a little bit of psychedelia, and a little bit of pop. Ultimately it didn't have a lot of significance, without memorable original material or a consistent or interesting style, though the playing and singing is competent, and the mood usually reflective. All of their members, though, went on to projects that made a more lasting commercial impact. Butch Trucks became drummer for the Allman Brothers; Scott Boyer played in Cowboy; and bassist David Brown went to Santana. ~ Richie Unterberger, Rovi
