Aerosmith

Despite a wild ride, this classic rock band, which formed when Steven Tyler met Joe Perry while working at an ice-cream parlor in 1970, had skated for decades -- until discontent became evident a couple of years ago. Amid stories that Tyler was on the verge of quitting, there were rumors that the band had contacted other famous singers about joining the band. And when Tyler became a judge on "American Idol" -- cheesing off Perry -- it seemed like this Beantown band was out of gas. But now the band is back with a new album, released last month.

In their favor: Tyler's "Idol" time introduced Aerosmith to new audiences.
Biggest threat: Perry becomes a judge on "The Voice."
