“It was great to work with Aerosmith after the success of Permanent Vacation, which was the first time I got a real shot at mixing.
"Permanent Vacation was the band's comeback record, and this was the one that would really put them back to where they were in the ‘70s.
“Joe Perry and Steven Tyler had both been sober for a couple of years now, and they were really on point with their songwriting. They co-wrote a few songs with people like Jim Vallance and Diane Warren.
"But the amazing thing about Joe and Steve is, no matter who they write with, the songs always sound like Aerosmith.
“As good as Permanent Vacation was, Pump is an even stronger record, in my opinion. It’s tougher and all the juice is there. The fun thing for me was working with the guys on all the little segues between the songs.
"Everything was played live. Joe and Steve got all of these interesting instruments like didgeridoos and various pieces of percussion – that was very cool working with them on those sounds.”
