The McCoys enjoyed a massive international hit with their first shot in the big leagues -- after producers Richard Gottehrer, Jerry Goldstein, and Bob Feldman discovered them when they shared the bill with the Strangeloves in Ohio, the McCoys landed a deal with Bang Records, and their first single for the label, "Hang on Sloopy," went all the way to number one. But the McCoys had grander musical ambitions than their patrons at Bang were willing to nurture, and in 1968 they signed with Mercury Records, where they were given complete creative freedom as they cut their final two albums, Infinite McCoys and Human Ball. The McCoys' musical approach took a 180-degree turn with these two albums, which blended psychedelic meanderings with jazz piano pieces, country melodies, sunny pop and extended blues workouts.
