That means you saw the Seasons in the Abyss solo played correctly by Gary Holt, and saw Jeff Hanneman play Angel of Death and South of Heaven with Slayer in the same set!? I'm calling this possibly Slayer's greatest set since they stopped doing 90 minute+ shows.
Brocas Helm/Hatchet/Exmortus/Midnight Chaser 11/22
High on Fire/Kvelertak 12/12
Exodus/Nails/Hellfire (???) 12/20
Neurosis/Bl'ast!/YOB (???) 12/29
