David "Gus" Griesinger of BackstageAxxess.com conducted an interview with AC/DC bassist Cliff Williams at this year's NAMM (National Association Of Music Merchants) show, a massive music-products convention that took place January 24-27 at the Anaheim Convention Center in Anaheim, California. You can now watch the chat below.

On when fans can expect a follow-up to 2008's "Black Ice":

Cliff: "[There is] nothing in the works right now. We're still getting over the last tour, so we're just hanging out and doing stuff. The guys [guitarists Angus and Malcolm Young] are writing material and when they've got some stuff together, they'll give us a holler."

On the AC/DC songwriting process:

Cliff: "[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."

AC/DC guitarist Malcolm Young last year confirmed to Classic Rock magazine that the band is working on the follow-up to 2008's "Black Ice". But he said fans may have to wait longer than expected.

"I've been doing some jamming on some song ideas but I do that all the time, as do the rest of the band," he said. "We are still working. But we had a long rest between 'Stiff Upper Lip' and 'Black Ice', so I think we need a couple of years to recuperate and work on it a bit more."

AC/DC's 25 albums became available digitally for the first time on November 19, 2012. All tracks were mastered for iTunes, and fans have the ability to download full albums or simply purchase their favorite individual songs. Fans can also choose from two specially packaged digital compilations: "The Complete Collection", the complete iTunes-exclusive AC/DC catalog; and "The Collection", which includes all 16 studio albums.
