The band's long time engineer has teased that the legendary band are up to something in the studio.
Rumours of new AC/DC music have been rife for a while now, but Mike Fraser's recent comments have added more fuel to the fire that the band have something up their sleeves.
The longtime engineer of the band revealed some interesting revelations during an interview last month with Australian podcaster Tony Mantz.
When asked about the rumours Fraser confessed: "Umm... Well, yeah, I could say that we've been in the studio doing something. What's come of that I can't discuss yet, but uh..."
Mantz pressed: "With Brian singing?" to which Fraser replied "I think so" coyly.

Fraser has been a longtime collaborator of the band and has mixed a whopping five AC/DC albums including their most recent 2014 release "Rock Of Bust".
He's also worked with the likes of Metallica, Led Zeppelin and Guns N' Roses in the past.
Rumours about new AC/DC music were born from pictures of singer Brian Johnson, drummer Phil Rudd, and guitarists Angus and Stevie Young taken outside Warehouse Studios in Vancouver.
Online reports and fans expect that any new music will be dedicated to the late Malcolm Young.
