Forest Hills Tennis Stadium in New York, 18 August 1965 |
It's just possible to make out Al Kooper and a Hohner Pianet to the left of Dylan. The legs indicate that it's a Mark 1, C, or CH model.
Seeing this picture reminded me that back in May, I discovered that there's Pianet on Dylan's Highway 61 Revisited album. I did some research and found a Keyboard Magazine interview* with Al Kooper from June 1977 that notes specifically that there's Pianet in "Just Like Tom Thumb's Blues." This is confirmed in Andy Gill's Bob Dylan: The Stories Behind the Songs 1962-1969, which also mentions that Kooper played "the galloping electric piano" on "Highway 61 Revisited." I believe there's Pianet in "Ballad of a Thin Man" too.
I listened to The Bootleg Series Volume 12: The Best of the Cutting Edge 1965-1966 to see if I could find any more instances of Pianet, and I'm pretty sure it's also present in "Lunatic Princess." The liner notes list simply "electric piano," again credited to Al Kooper.
There's electric piano in some songs on Bringing It All Back Home (and in "If You Gotta Go, Go Now" on The Best of the Cutting Edge), but these were recorded before Al Kooper started playing with Dylan. The Best of the Cutting Edge credits Frank Owens and Paul Griffin on these tracks. While the electric piano is often buried in the mix on Bringing It All Back Home, it sounds more like Wurlitzer to me. Based on the Keyboard Magazine interview, it seems that Kooper was the one who introduced the Pianet into Dylan's sound.
