Pop-punk outfit Relient K [ tickets ] will spend this spring and summer on tour behind its most recent release, last year's double EP "The Birds and the Bee Sides."

The trek will pass through 28 cities over the next four months, including two Canadian stops set for May 22 in Edmonton, Alberta and June 27 in Vaughan, Ontario. Details are below.

Relient K will share the stage for most of the run with fellow indie rockers Owl City, The Classic Crime and Runner Runner.

Released last summer, the double-disc"The Birds and the Bee Sides" took the No. 1 spot on Billboard's Top Christian & Gospel Albums chart. Vocalist/guitarist Matthew Thiessen doesn't shy away from the "Christian pop" label that the band has been stamped with since their 1998 debut.

"Whatever people want to call us, they can call us," Thiessen told LiveDaily in an interview last summer. "I'm Christian. I write a lot about that stuff. I think it's important for me in my life and we obviously want to write songs about things that are important. At the same time, if you don't share the same beliefs as us, you're probably not going to get rubbed the wrong way with our music."

The band, which broke into the Top 15 on The Billboard 200 with two albums--2004's "Mmhmm" and 2007's "Five Score and Seven Years Ago"--are working on a new studio album for release later this year. The group's MySpace page currently features webisodes of recent studio sessions.
