Sum 41 spreads its infection with more dates

Sum 41, which in mid February kicked off its latest round of tour dates behind last year's "Does This Look Infected?," has extended the run into early May.

In addition to its lengthy roster of headlining engagements, the Canadian rockers will also get away from the Great White North with a June 28 performance at this summer's annual, multi-day Summerfest event in Milwaukee.

The group plans to announce additional dates in the coming days, according to its website.

In late November of last year, Sum 41 released its sophomore effort, "Does This Look Infected?" The CD is packaged with a limited-edition DVD that contains more than 80 minutes of band footage, and also includes a live EP.

The new album features the single "Still Waiting," the music video for which is streaming at the band's website. The album's second single, "The Hell Song," hit radio stations earlier this month, and is also streaming at the group's site.

"Does This Look Infected?" is the follow-up to Sum 41's 2001 major-label debut, "All Killer, No Filler," which spawned the group's breakthrough hit "Fat Lip."
