Al Kooper, leader of the pioneering New York band, the Blues Project, had an idea for an adventurous rock-jazz big band. Their debut album was a promising start, but then Kooper decided to leave his own group. The rejuggled BS&T recruited leather-lunged vocalist David Clayton-Thomas, went in the studio with James William Guercio, and promptly achieved incredible success. In addition to the Motown cover, “You’ve Made Me So Very Happy,” the self-titled collection leaped from Billie Holiday to Laura Nyro to band originals with aggressive zest.
