Kerry King is one of Slayer's founding members and is responsible for some of metal's most iconic guitar riffs.
King is an outspoken atheist with anti-religious views and many of his band Slayer's songs feature controversial lyrics about dark and disturbing subject matter.
'Psychopathy Red' is a leaked track from Slayer's forthcoming tenth studio album World Painted Blood. Both the violent lyrical content and intense instrument work demonstrate that Slayer are in no way toning their music down, despite having been around for nearly three decades.
Slayer played a sold-out show in Auckland last night alongside fellow classic thrash metal band Megadeth.
