He said, while doing press to promote his solo band, The Joe Perry Project: “It was just taking Aerosmith so long to get that album out, and I was so fed up with that because in the meantime all during the summer we played these gigs and couldn’t play any of the new material because it wasn’t ready.
“Instead we had to go back and do the same old songs.
“It came down to I called up Tom Hamilton and said, ‘It’s off, I just don’t think I’m going to be able to go on the road with you this time, I’m going to stick with my own solo thing and I can’t put up with it anymore.’ That was the last official word I said to the group.”
In 2011 he echoed these sentiments, telling The Guardian: “When I first quit the band I thought, ‘What the f**k?’
“‘I’ll just go out and tour.’ But going solo is a lot of work. That was a big learning process.
