Oh BTW, I found the quote from Flood.

https://tapeop.com/interviews/115/sm...tudio-history/

Flood: When you watched them live, at that time, during Mellon Collie..., I don't think I've recorded a better band. They were so amazing, but it had to be all four of them there. They all needed each other in different ways. The groove and the feel of the combination of all of them; when they were really on it, nailed it, and knew what they were doing, it was amazing.

AND

Billy Corgan: Most producers usually get out of the way with me with guitars. They know that I'm a charging bull there. They don't have a whole lot to work to do with me on the guitar, so one could argue I've rarely been produced on the guitar. Vocally, however, I think I've benefited from working with great producers like Flood, who've gotten the best out of me as a vocalist. I probably haven't done as good a job when I've produced myself.

(sounds about right)
