Like a Rolling Stone
Bloomfield also made an impact through his work with Al Kooper, who had played with Bloomfield on Dylan's "Like a Rolling Stone". Kooper had become an A&amp;R man for Columbia Records, and Bloomfield and Kooper had played piano on Moby Grape's 1968 "Grape Jam", an instrumental album that had been packaged with the group's "Wow" collection.
