SLAYER played a cover version of the EXODUS classic "Strike Of The Beast" for the first time ever last night (Sunday, July 1) at the Mountain View, California stop of the Rockstar Energy Drink Mayhem Festival. Fan-filmed video footage of the performance can be seen below.EXODUS guitarist Gary Holt has been filling in for SLAYER's Jeff Hanneman for the past year and a half while Hanneman recovers from necrotising fasciitis, a flesh-eating disease, which he got from a spider bite. In a recent interview with Full Metal Jackie's nationally syndicated radio show, SLAYER guitarist Kerry King stated about Holt, "I always regard Gary as the Glenn Tipton of our era — really good, really polished and nobody talks about him. To this day, nobody really references [JUDAS] PRIEST and Tipton that much as guitar players and I feel the same way about Gary. EXODUS have a huge following but a little more overlooked than METALLICA, MEGADETH, SLAYER, ANTHRAX — the 'Big Four,' so to speak, so [it's great] to be able to bring him to the forefront and shove him down people's throats and say, 'Hey, this motherfucker kicks ass. Pay attention.'"
