Aerosmith have since regrouped to record the new album Music from Another Dimension, which Tyler credited with smoothing over any personality conflicts.
"Joe and I were fighting for a while, that's no secret. But whatever demons or realities were going on in the band, it happens with bands that stay together for 40 years and have the success that we have," Tyler told PA.
Guitarist Perry also admitted that the 'Walk This Way' band have always had a complicated dynamic, but their on-stage chemistry continues to bind them together.
"It's only as good as those two hours on stage. The rest of it, I have no idea how it works," Perry joked. "With Aerosmith, we put one foot in front of the other and hope for the best."
