AC/DC brothers Angus and Malcolm Young are currently hunkered down in a U.K. studio working on the band's brand new studio album, Launch Radio reports.

The Aussie rockers have amassed so much material that the new as-yet-untitled effort may turn into a double album.

"I think, and I might be speaking out of turn, but I think they're doing a double, with the amount of songs, singer Brian Johnson told Launch. "I've been over a couple of times with the boys and added ideas on 46 tunes we had, and they've been working since then."

There is no scheduled release date as yet, but the band plan to tour in support of the disc when it comes out.
