HIGH/LOW: Sex, drugs...well, you know (1976)
Aerosmith follows up Toys in the Attic with Rocks, which reaches No. 3 on the Billboard chart. The re-release of an older song, ''Dream On,'' charts at No. 6, 53 spots above its original peak in 1973. The success is infamously coupled with one of the band's most destructive periods. They develop a reputation for heavy drug and alcohol consumption.

HIGH/LOW: Song for space movie puts band in orbit (1998)
The band's song ''I Don't Want to Miss a Thing,'' from the 1998 movie Armageddon, is the band's first song to debut at No. 1. While it was a commercial hit, longtime Aerosmith fans call the tune out-of-character. Before the soundtrack's release, EW's review called the song ''formulaic'' and ''grandly orchestrated''.

HIGH/LOW: All is well? (summer/fall 2009)
The long-awaited Aerosmith tour begins, with word from Tyler that the band is working on its first original material in more than seven years. But a string of injuries, most notably Tyler's fall from the stage during a show in South Dakota, postpones many dates. In November '09, Perry claims via Twitter that Aerosmith is looking for a new lead singer. Tyler refutes the claim hours later at an event hosted by Glamour magazine and then again on stage with Perry, saying ''I am not leaving Aerosmith!'' But Perry then tells People ''Nothing has really changed between two days ago and today.... Things are still up in the air.''
TELL US: What do YOU think? Should Perry and Tyler stop their ''Cryin''' and make up for good? Do you care? Sound off below.
