"Billy [Corgan, vocals/guitar] was fantastic. He comes with a very bad reputation to work with, just as being difficult. I said to him about it and he said, ‘Look, there’s two things I can’t do, I can’t play drums and I can’t mix. So I get people I know to do those things that do them well.’ He has no problem with people doing work with him, as long as they come in with the right agenda. If people are coming in trying to use his music as a showreel for themselves first and the project second, that’s where he has the problem.

“It was such a fun mix to do. It was very old school. We used three consoles, all linked together. We had two 16-track 2-inch tape machines and Pro Tools going at the same time. There was no automation, no computer mixing, no recalls - he never recalls at all. If he doesn’t like the mix he’ll do it again. It was a performance that mix; with no computers you had to do it all in one go, like back in the early '80s.

"On the first mix he came in and said, ‘Yeah, that’s pretty good, but there’s something not right with this section.’ It was the guitar solo section and I said maybe the guitar solo was a bit too loud and he said, ‘Oh no, the guitar solo is never too loud!’ He laughed, he was joking but he wasn’t! I cranked the rhythm guitar a little more on that mix to give it more edge and he came back and said, ‘Oh yeah, that’s my band.’ He was a pleasure to work with.”
