I personally bought the OBC album before Dark Side of the Moon came out and fell in love with it, seeing Pink Floyd in concert 1972 and not knowing about Dark Side forthcoming release makes me feel fortunate to have experienced the band before they blossomed into a phenomenon. Wots…uh the Deal has been my all time favorite song of any group and the rest of the album ranks pretty high also. Obscurred way not be a technical marvel but sets the stage for the world changing bombardment of albums to come by Pink Floyd
