SLAYER announced that Gary Holt from EXODUS will be the guest guitarist, temporarily filling in for Hammeman who is currently recovering from surgery. Holt will immediately join the band for their five-date Australian 'Soundwave Festival' tour that begins February 26.
Hanneman underwent emergency surgery on his right arm late last month after contracting a serious infection, possibly caused by a spider bite. He is now recuperating at home and is expected to make a full recovery. He will return to the Slayer line-up as soon as he has fully recovered.
