I remember that too.
Used to be in fairly regular contact with Buell and he talked about it to me some, though I don't believe we discussed it in our interview.
I didn't "get" Infinity when I first heard it and much preferred "Living Space," for example, without the strings. Now, I'm feeling a little more "like" if not "love" for Alice w/ strings and maybe could handle it. I assume that Alice felt she was carrying on some of the work that Trane had wanted to do w/r/t strings, but I don't know that for sure.
