Diabolus in Musica
It is considered to be Slayer's most experimental album with most of the album's content written by guitarist Jeff Hanneman. Hanneman described writing for the album as, "When we were writing this album I was looking for something to beat; I wanted something to beat, but nothing impresses me right now. Nothing sounded really aggressive or heavy enough to inspire me to beat it, so I just had to come up with my own shit."
