IT’S OFFICIALLY CHRISTMAS! When you think of Slayer, you think of Wham…right? Mashup master Bill McClintock mashed together both groups for a cheery, festive song. Slayer’s “South of Heaven” and Wham’s “Last Christmas” get pushed together for “Slam! – “South of Christmas.” Things take an interesting turn when Rammstein pop up too. It all actually works well together. Check out the mashup on Youtube and TRY not to feel jolly.
