Tom Araya from Slayer confirmed with Revolver recently that the late Jeff Hanneman’s playing will in fact appear on Slayer’s next album. They had started working on it three years ago and got a little bit of contribution from Jeff before he passed.
“The whole process of this album started three years ago, when Jeff was still a part of it. There is one track on there that we recorded with him, that he did play on, which was completely done except we hadn’t finalized the vocals for it. So we were fortunate to have something that he had participated in.”
