Punk outfits Good Charlotte [ tickets ] and Sum 41 [ tickets ] join forces this fall for a co-headlining run that will feature Hazen Street and Lola Ray in the opening slots.

The outing gets underway in Seattle on Oct. 21, and dates are confirmed through early November, with more shows expected. Tickets for many of the concerts hit the box office this coming weekend; details are shown in the itinerary below.

By the time they hit the road, Good Charlotte and Sum 41 will each be supporting new albums. Good Charlotte's "The Chronicles of Life & Death" is due in stores on Oct. 5, while Sum 41's "Chuck" is scheduled to surface on Oct. 12.

To usher in "The Chronicles of Life & Death," Good Charlotte will make a series of early October in-store appearances at Tower Records locations in New York City; Cherry Hill, NJ; Rockville, MD; and West Hollywood, CA. Details are available at the band's website.

"The Chronicles of Live & Death" is the follow-up to 2002's double-platinum "The Young and the Hopeless."

"Chuck," Sum 41's follow-up to 2002's "Does This Look Infected?," is named for Chuck Pelletier, a United Nations representative who helped to evacuate the group from its May trip to the Democratic Republic of the Congo, where it was shooting a documentary about that country's longstanding civil war with the nonprofit group War Child Canada.

The band arrived during a time of cease-fire, but violence broke out while they were in the country. "[Pelletier] herded the band into the lobby, then ran with them through gunfire to an armored tank and eventually to safety," said a press release issued by Island Records.

Streaming-audio and streaming-video versions of "We're All to Blame," the first single from "Chuck," are posted at Sum 41's website.
