AC/DC haven't exactly been the hardest-working band in show business over the last few decades. The legendary Aussie rockers have only released three albums since 1990, and their last album was 'Black Ice' in 2008. But in a new interview, bassist Cliff Williams says guitarists Angus Young and his brother Malcolm have been working on some new material -- though he stops short of promising a timetable for a new album.

“[There is] nothing in the works right now [as far as recording],” Williams tells BackstageAxxess (quote via Loudwire). “We’re still getting over the last tour, so we’re just hanging out and doing stuff. The guys are writing material and when they’ve got some stuff together, they’ll give us a holler.”

The bass players adds, “[Angus and Malcolm] get a bunch of ideas together. Some are more together than others — and then we’ll all hit the studio or a little rehearsal room and we’ll kick it around with a producer. And then we get in a studio and record, and that’s kind of how it runs. The guys, I’m sure, are putting their time in [writing material for the new album] — Malcolm and Angus — but they’re not ready for [the rest of the band to get involved] yet.”

Still, it's a step forward from last June, when Angus Young put the kibosh on rumors of a new album after singer Brian Johnson dropped a hint that one might be in the works.
