Details of the long-awaited new U2 album, including a tentative release date, are starting to take shape. According to Billboard, the group is apparently searching for a partner to announce the new project during a Super Bowl commercial early next year.

The untitled album, which bassist Adam Clayton said would include 12 songs, could be out as early as April.

But it appears that the band isn't working with Brian Eno and Daniel Lanois, the team that oversaw some of U2's greatest triumphs, including 1987's 'The Joshua Tree,' 1991's 'Achtung Baby' and 2000's 'All That You Can't Leave Behind.'

Instead, they're working at New York's at Electric Lady Studios with producer Danger Mouse, who's collaborated with Gnarls Barkley and the Black Keys in the past. The producer (born Brian Burton) got his big break with the mash-up record 'The Grey Album,' which combined Jay-Z and the Beatles.

U2's last album, 2009's 'No Line on the Horizon,' debuted at No. 1. The group has previously announced the Nov. 29 release of a new song called 'Ordinary Love' for Black Friday's Record Store Day. That track is part of a new biopic, 'Mandela: Long Walk to Freedom.'
