Shared fascination here! I have the "incomplete" Savoy original CD (without the ballads variations, "Circle With The Hole..." and, especially, "Stereophrenic", great cut. Should track down this "complete" edition...). Liked what Steve Swallow recently had to say about the date (https://jazztimes.com/features/columns/steve-swallow-pete-la-roca/):
Paul Bley, Footloose! (Savoy, 1963) — “Paul and I had been playing that repertoire extensively as a duo for several months. I got Pete on the date and ended up being the musical interlocutor between Paul and Pete. Pete was upholding the value of swing, while Paul was straining at those boundaries, even though he could get a merciless groove going if so inclined. There was wonderful electricity in the air; I love that record.”
