It's been seven years since Joan Jett has released an album, but that streak will end with the Oct. 1 release of 'Unvarnished.' The rock legend reteams once again with her band the Blackhearts, and the album also features collaborations with Foo Fighters drummer Dave Grohl and Against Me!singer Laura Jane Grace.

The 10-song album opens up a new chapter in the 54-year-old's journey, as the collection will deal with its share of weighty themes, most notably the inevitability of loss. "I'm in a different part of my life," said Jett in an interview with The Modesto Bee. "The songs aren't all sex, drugs and rock 'n' roll. There comes a time when you have to go through stuff. For me -- this isn't very uplifting -- but I call it the decade of death, losing people, companion animals very close to me, my parents, really heavy things."

A co-founder of the all girl band The Runaways, Jett also stepped back in the movie business (she starred in the Michael J. Fox film 'Light of Day') as an executive producer on the film 'The Runaways,' which featured Kristen Stewart playing the frontwoman.

Songs on the new album include 'Any Weather,' a track she crafted with Grohl, as well as 'Fragile' and 'Hard to Grow Up.' "Some things shock you into recognizing and realizing you've got to grow up," added Jett. "Responsibilities fall to you. You've got to either stand up or not. I want to be someone who steps up."

In support of the upcoming album, Joan Jett and the Blackhearts will perform 'Any Weather' on 'Jimmy Kimmel Live!' come Aug. 8.
