Aerosmith are on the road this summer playing their Global Warming tour across North America with Cheap Trick.

Prior to the start of the tour, the band issued a new single, “Legendary Child,” which will appear on their forthcoming album, “Music From Another Dimension.”

The Boston rockers recently moved the release date from August 28 to November 6, and guitarist Joe Perry is happy for the breathing room.

“We’ve had all kinds of problems over our career, and I mean all kinds, and having to wait a few months for the new record to come out is the best problem we’ve ever had,” Perry told the Boston Herald.

Steven Tyler’s role as a judge on American Idol may have, at first, seemed like a hindrance to the band’s schedule, but with the benefit of hindsight, Perry is now on board with the whole thing.

“We worked the band’s career around ‘Idol,’ but that worked for us,” he said. “It gave us defined times we had to work, and I was already planning on being in L.A. to do some soundtrack work for TV and film. The timing worked perfectly, and lo and behold, we got to finish the record.”

Reports suggest Aerosmith have dipped back into the sleazy ’70s rock at which they excelled.

“People didn’t think we had it in us,” said Tyler. “But, by the grace of God, (producer) Jack Douglas was available. That first year I was doing ‘Idol,’ Jack happened to be working at a studio, Swinghouse, here in Hollywood, we did four, maybe five months with Jack, just like old times, and it worked.

“There’s no doubt he has a vision of how things should sound,” Perry said of the producer who helmed “Get Your Wings,” “Toys in the Attic” and “Rocks.” “We fight with Jack and with each other still. But if we didn’t, the album would sound like (expletive). We were trying to prove something, we were fighting over songs, but that’s how you make a great album.”
