U2 is in the midst of an extended songwriting and recording session in Fez, Morocco, with longtime collaborators Brian Eno and Daniel Lanois. Sources say the band has already flashed out a number of ideas, but, writing on U2.com, Bono claims it's still too early to tell whether any of them will appear on U2's next studio album.

"We have no plans for the music yet," he said. "We're just going to make it until we can't not put it out!"

Although Eno and Lanois have respectively worked with the band on some of its most classic material, they have never previously teamed with U2 in a "purely songwriting capacity," according to drummer Larry Mullen Jr. "So it's very different, quite experimental and kind of liberating because of that."

U2.com is promising an insider's look at the sessions throughout June. Meanwhile, the band recently previewed its upcoming concert film, "U23D," at the Cannes Film Festival in France.
