It was previously revealed that one track on the follow-up to 2009's World Painted Blood was written before Hanneman's death, and features his playing.

Araya tells Revolver: "The whole process of his album started three years ago, when Jeff was still a part of it. The track was completely done, except we hadn't finalised the vocals for it. So we're fortunate to have something he had participated in."

A total of 13 songs have been laid down by Araya, Kerry King, Gary Holt and Paul Bostaph, although it's likely only 10 will appear. Slayer have still to decide on the album title, artwork and other details.
