It’s official–Radiohead have begun recording their ninth studio album.

On Wednesday, producer Nigel Godrich tweeted a photo of lead singer Thom Yorke with Jonny Greenwood in the studio experimenting with modular synthesizers, a hint that the Grammy-winning rockers are returning to electronic territory.

Earlier this year, the group suggested that recording on their follow-up to 2011’s “King of Limbs” would start in September but this black and white image is the first confirmation that Radiohead are, indeed, working together again.

Greenwood, in a recent interview with The Sunday Times, said there were no official plans for the album’s release.

“Release? No, no idea. No,” he said. “Our plan is to start making music soon. We’ve just got to get the inertia back.”

In the meantime, members of Radiohead kept busy working on their own individual music.

Yorke released his solo effort, “Tomorrow’s Modern Boxes,” in September while Greenwood recently scored Paul Thomas Anderson’s new film “Inherent Vice.” Drummer Phil Selway also issued his second LP in October.

It’s unclear how Radiohead intends to release the new material. The U.K. group stunned the music industry when they self-distributed their last two albums, “In Rainbows” and “King of Limbs,” in an effort to bypass corporate labels.
