This fall, concertgoers can get a double dose of the rock when Sum 41 and Good Charlotte hit the road together.

The co-headlining tour kicks off October 21 in Seattle, according to the bands' publicists. A dozen shows are confirmed so far, with additional dates expected to run through the end of November. Tickets go on sale beginning Friday.

Hazen Street, the first signing to Benji and Joel Madden's D.C. Flag imprint, will serve as openers (see [article id="1480455"]"Hazen Street: Pop Punks And The Guys They Worship Make Music Together"[/article]). The band's self-titled debut dropped in July.

Good Charlotte and Sum 41 will each hit the road on the heels of new albums: The Chronicles of Life and Death and Chuck, respectively. Good Charlotte are actually releasing two versions of their third album on October 5 (see [article id="1489850"]"Good Charlotte Get Serious With The Chronicles of Life And Death"[/article]). The Life version contains the bonus track "Falling Away," an optimistic rave-up, while the Death version finds fatalistic "Meet My Maker" tacked onto the standard album's 15 tracks. Guitarist Billy Martin, the band's resident artist, created the cover art for both versions.

"The CD is laid out like an old storybook, where the lyrics sort of tell the story and the illustrations go along with each song," Martin explained. "The art on the cover of the Life CD represents more of a new book, like a book when it first gets printed. And the death one looks like the book is 100 years old and it's falling apart and it's getting ready for the end of its time."

Both "books" won't be around forever. Eventually, one of the versions will disappear from store shelves, making it something of a limited-edition collector's item.

"I love when bands come out and do the special editions and multiple album covers," Martin said. "You don't get to put a record out that much, so we wanted to do something cool."

As for Sum 41, their latest, Chuck, named for the U.N. peacekeeper who may have saved their lives on a humanitarian visit to the Congo earlier this year (see [article id="1490417"]"Sum 41 Name Album After The Man Who Saved Their Lives"[/article]), will drop October 12. Its first single, "We're All to Blame," is beginning to heat up radio playlists, and a video surfaced this week.

A classic hardcore flurry opens the song, which focuses on the world's problems and points the finger at our own personal greed. "We've gone from pride to shame," frontman Deryck Whibley sings before dropping buzzword-laden phrases like "Supersize our tragedy" and "We live in a culture of fear." Despite the matured, socially responsible themes in the single, Sum 41 haven't lost their trademark sense of humor. The "Solid Gold" dancers -- from the glitzy, overwrought lip-synch performance show of the 1980s -- in the video kind of give that away pretty quickly.

"The video is pretty funny," Whibley said. "There are so many sides to our band. We try to be aware of things and we have kind of a message in some of our songs, but we're still a humorous band, and we like to have fun in our videos and do something creative. So in this video we're playing on 'Solid Gold.' The whole stage is set up the same. We really don't have to do much except play; the dancers do all the work."
