Coldplay is putting the finishing touches on its third studio album, expected in March or April via Capitol. Initial sessions for the as-yet-untitled set with producer Ken Nelson were set aside, with the U.K. rock act opting to start over with producer Danton Supple, who mixed Coldplay's 2002 breakthrough, "A Rush of Blood to the Head."

"It's been quite turbulent," frontman Chris Martin tells NME of the sessions. "We've been through a lot of songs and a lot of sounds, a lot of studios. It took us a long time to realize the four of us should go into a rehearsal room again and play together rather than rely on technological assistance."

Among the tracks earmarked for the album include "The Hardest Part," "Square One," "'Till Kingdom Come," "What If," "X&Y" and "Talk," which is said to feature the main riff from Kraftwerk's "Computer Love."

Coldplay is expected to make its return to the live stage, possibly armed with new material, as part of a March 12 benefit for California radio station KCRW in Los Angeles.
