Irish rock legends U2 are said to be recording a new album that will have a distinctly “futuristic” sound according to RedOne.

RedOne, who is producing the latest album for the award winning act, confirmed to Billboard during an interview that he was working with U2 again and was collaborating in a project with the band.

He told Billboard: “We have put down a few ideas, but we don't know how many will end up on there.”

RedOne added: “They have a very special way of working. A song is never done until the day before it comes out almost, so you never know.”

When talking about the latest U2 project he said: “They are always experimenting, so it's not like “OK, we're finished”. It is still an ongoing process. Bono described the album as futuristic. U2 going sci-fi, or something. That's how he described it, but I don't know.”

U2 are due to headline the Glastonbury festival this year after being forced to pull out previously. Other headlining acts confirmed for the iconic British festival include Coldplay and Beyonce.
