Steven Tyler says "it's beautiful" when Aerosmith reunite on stage, as "all the cr*p melts away".

The 64-year-old frontman caused a feud with his bandmates in 2010 when he joined the judging panel of American Idol without informing them first.

Steven and guitarist Joe Perry openly fell out in public, but Steven is now glad they've come together on their fifteenth studio album Music From Another Dimension!.

"A year ago, nobody wanted to do an album," he told USA Today.

"Now we're all on the same page and we've been burning the candle at both ends. It all comes together when the band gets on stage. It's nothing but beautiful and all the cr*p melts away. That's when the band is a band, no matter what else is going on."

Joe agrees with the sentiment. The star says arguments are not always detrimental to the success of the band.

"We don't agree on everything. But the machine is bigger than the parts. We all know that. We sorted out what we had to sort out," he explained.

"Some personal things got overblown and a few things got misconstrued. We've been working together on the record for the last four months. Hey, if we didn't have disagreements, something would be wrong and the record wouldn't be what it is."
