Yeah, that band is one of my earliest musical memories. I picked up a couple albums when free shipping was offered from a Discogs seller of an old jazz album I wanted.
I got this album too. Still waiting for Jupiter and Mars to line up though.
My older sister bought that when it first came out. Being a double album, there was a lot of material there and at least one of those album sides was playing pretty much nonstop for weeks. It's a musical masterpiece.
