5. Slayer, Diabolus In Musica

Following the three-album hat trick of Reign in Blood, South of Heaven and Seasons in the Abyss, Slayer became a band that could do no wrong – or at least until Diabolus in Musica came out in 1998. The next to last album to be released before drummer Dave Lombardo rejoined the fold, it’s about as close to trying to fit in with current trends as Slayer ever came. However, the current trend at the time was nu-metal, which led to fans accusing the band of selling out. That was enough for them to return to heaviness with 2001’s God Hates us All and to stop playing anything from Diabolus.
