Blood, Sweat & Tears began as Al Kooper's dream of a rock band with horns. By the time he realized the concept—on the band's 1968 debut, Child Is Father to the Man—it had become much more: an engaging hybrid of New York soul, Greenwich Village folk, and innovative jazz arrangements. With producer John Simon at the helm, Child was a virtual definition of the possibilities inherent in the heady musical experimentation of the late 1960s. Kooper's writing and arranging for that record (including the monumental "I'll Love You More Than You'll Ever Know," later a hit for Donny Hathaway) is one of the high points of his storied career.
