Michael Bloomfield, Al Kooper, Stephen Stills, 'Super Session' (1968)
Three years after collaborating with Bob Dylan, Al Kooper and Michael Bloomfield decided to unite for a somewhat free-form recording session in which they would record a full album in two days. Kooper was looking for a new project after his departure from Blood, Sweat & Tears, and had hoped to record Bloomfield in a way that captured the guitarist's superior live improvisations. Backed by two of Bloomfield's Electric Flag bandmates, keyboardist Barry Goldberg and bassist Harvey Brooks, as well as drummer Eddie Hoh and session horn players, they recorded six songs, including the Coltrane-inspired keyboard workout "His Holy Modal Majesty." The next day, however, Bloomfield didn't show up to the studio and Kooper called in Stephen Stills, who had recently departed Buffalo Springfield, to play guitar on a handful of covers including Bob Dylan's "It Takes A Lot to Laugh, It Takes A Train to Cry" and a funky extended version of Donovan's "Season of the Witch." The resulting masterpiece featured Bloomfield on the LP's first side and Stills' work on the other, and peaked at No. 12 on the LP charts. It's a precursor to today's jam band efforts.
