I saw SLAYER three weeks ago at Ozzfest in Poland. Dave Fucking ruled, he's surely one of the best drummers out there. The whole band was awesome too and the crowd was just insane, singing every song with Tom (although most of them came to see Ozzy, not Slayer). Fortunately they only played "Disciple" from the newer songs (which is the one that sucks the least) at the beginning and then all the classics: "postmortem", "raining bloo", "war ensemble", "angel of death", "dead skin mask", "south of heaven" and others- the crowd just wouldn't let them go away, but they had to leave some time before Ozzy for Tool, which was OK, but didn't kick ass as much as Slayer, Decapitated and even Ozzy.
I hope TestAmenT comes to Poland soon
