Prog-rockers Coheed and Cambria have added another round of US dates to their international tour supporting "No World for Tomorrow."

The band will finish its current North American outing this week and then head to Europe in June. Following a July 2 performance at Milwaukee Summerfest, Coheed and Cambria will launch a two-week US trek that stretches from California to South Carolina. Secret Machines and Russian Circles will open most of the stateside dates, which are listed below. Overseas shows can be found at the group's website.

Coheed and Cambria have been making their way around the world all year to back their latest album, "No World for Tomorrow," which surfaced in October and reached No. 6 on The Billboard 200. The set has spawned the mainstream- and modern-rock hit "The Running Free," which is streaming at the rockers' MySpace page. A new band-created video for the tune "Gravemakers and Gunslingers" can also be found there.

"No World for Tomorrow" marks the final chapter of a four-part saga created by Coheed and Cambria mastermind and frontman Claudio Sanchez. The storyline, which is also captured in Sanchez's "Armory Wars" comic book series, follows a doomed married couple who are convinced they must sacrifice their children to save the world. The saga has unfolded through C&C's earlier efforts: "The Second Stage Turbine Blade" (2002), "In Keeping Secrets of Silent Earth: 3" (2003) and "Good Apollo, I'm Burning Star IV, Volume One: From Fear Through the Eyes of Madness" (2005).

Sanchez also recently debuted a new comic strip, "Kill Audio," on MySpace. The first four mini-issues in the series will be included in Image Comics' collaborative graphic novel "PopGun" this summer, according to a press release. In addition, Sanchez plans to introduce a limited-edition vinyl toy of Kill Audio at July's San Diego Comic-Con.
