Mike Bloomfield
Prokop moved to Toronto and organized a band, the Paupers, who began playing in Yorkville coffee houses, and later performed in New York and at the U.S. Monterey Pop Festival in 1967. The Paupers were managed by Albert Grossman. He introduced Prokop to Al Kooper. Grossman asked him to leave The Paupers to play drums with Kooper and Mike Bloomfield for a follow-up recording to "Super Session". The result was "The Live Adventures of Mike Bloomfield and Al Kooper", a live late-1960s blues-rock album.
