Final Mix.

AEROSMITH: Done This Week?

Joe Perry hopes to be done mixing the new Aerosmith album, Music From Another Dimension, this week. He also says Steven Tyler is "singing better than ever," but adds that he isn't the only vocalist on the disc. Perry sings one song and duets with Tyler on another, and says there's "something for everyone on the new CD."

There's also a rumor that one song will feature a duet with country singer Carrie Underwood, who Tyler has performed with twice -- at the ACM Awards and on an episode of CMT Crossroads.

The album will be out on August 28th.
