British alt-rockers Keane [ tickets ] continue to issue make-good dates on a North American tour that never happened last year, with a new slate of shows set for later this spring.

The trio has lined up 11 dates in May, kicking off with a May 11 Los Angeles show, to help make up for the cancellation of a US/Canadian tour that was scheduled to run from September through December. Keane also played five make-up shows in January.

Pre-sale tickets for the new dates will be available starting today (3/21) through the band's official website.

The group initially postponed, and then canceled, its planned fall tour of North American so that frontman Tom Chaplin could undergo treatment for drug and alcohol addiction. The band's members said in a statement that they felt it was important to not pressure Chaplin to rush his treatment.

"It'll be great to get back out to America and Canada," Chaplin said in a press release. "We were all really disappointed to miss out on the big tour in September, so it's genuinely exciting to be going out again. It's long overdue and we're really looking forward to it."

Keane's sophomore album, "Under the Iron Sea," was released in June and entered The Billboard 200 chart at No. 4. The album's fourth single, "A Bad Dream," was released in late January; a live version of the track is streaming at the band's MySpace page.
