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 below and TRY not to feel jolly.
