From a great interview that SPIN magazine did with Moogfest creator Ashley Capps of AC Entertainment:
Are there any further announcements to come?
There are still some discussions that are being had that I’m trying to finalize. One of them I can’t announce, but he rarely performs in public these days. I’m not sure what he’s going to do; he might just play acoustic piano. But we can go there, if that’s what he wants to do. The first year we had Van Dyke Parks, and you know, Van Dyke was one of the early experimenters with the Moog, back in the 1960s, and he was a close friend of Bob’s, but when he came to Moogfest, he just played his classic tunes sitting at the piano. It was like a somewhat eccentric look back on 100 years of American music, and it was just great. We feel like most of our focus needs to be on that kind of electronica, but not all of it.
get Tom Waits!
