It's a running joke that each and every story about Dave Lombardo on blabbermouth.net includes this paragraph:
Lombardo was effectively fired from SLAYER after sitting out the band's Australian tour in February/March 2013 due to a contract dispute with the other members of the group. He has since been replaced by Paul Bostaph, who was previously SLAYER's drummer from 1992 until 2001 and recorded four albums with the band.
What I think always gets lost in the "Dave v. Paul" rants and comments is that it takes a drumming skill higher than most ranters and commenters can even hope to attain to play the drum parts of Slayer songs. This is evident below as Paul wails away on "Dead Skin Mask." I've always loved the ride cymbal bell note during this song. It's a little nuance Lombardo initially put into the song that added a different color to the song.
And Slayer seems so down-to-earth...
