U.K.-based rock act Kaiser Chiefs has canceled a week's worth of U.S. and Canada concert dates in September to focus on the follow-up to its sophomore album, "Yours Truly, Angry Mob," according to a spokesperson for the group.

The five-piece group will use the time off to complete new material for its as-yet-untitled album, prior to the launch of a European arena tour, scheduled to begin Oct. 29 in Germany and wrap Dec. 16 in the United Kingdom. Since its release in February, "Yours Truly, Angry Mob" has sold 82,000 copies in the United States, according to Nielsen SoundScan. The set debuted and peaked at No. 45 on The Billboard 200.

The band is still, however, scheduled to perform Sept. 14 at this year's Austin City Limits Music Festival at the Texas capital's Zilker Park. Kaiser Chiefs will also perform at New York's Beacon Theatre on Sept. 29, with support from White Rabbits and Datarock.

"We'd like to apologize to fans in America and Canada, especially those who have already bought tickets, but something had to give," Kaiser Chiefs drummer Nick Hodgson said in a statement. "We've been extremely busy all year and had no time to focus on the future, we plan to have new material out as soon as possible and we've wanted to record all summer."

"This needs to happen before our European and U.K. shows at the end of the year so we can play a few of our new songs live, we're keen to explore new ground, beyond the sound of our first two records, so we're headed back into the studio to begin that process," Hodgson continued.
