Rumors of a new AC/DC album have been heating up ever since photos leaked of various members of the group at Vancouver’s Warehouse Studio. Brian Johnson also added fuel to the fire after reportedly telling Terrorizer that the rumors were true. Now, a photo has surfaced suggesting that Cliff Williams was involved in the album, despite his retirement. The image shows Williams and Johnson with a trainer at a Vancouver hotel, and it is believed to have been taken around the same time as the apparent recording sessions. If true, the rumored album will feature Johnson, Williams, Phil Rudd, and Angus Young. Some reports have even said the effort will feature the late Malcolm Young on every song as well.
