Both times I've seen Slayer, Holt was playing. He's awesome. However, second time I've seen them was with Bostaph who was pretty bad imo.
Thanks for answering. I'll pay attention to his play next june. Anyway, good or not, getting rid of Lombardo is a stupid move. The man is awesome and knows what a song needs : I was listening to South of Heaven recently, and it's amazing to hear how he can alternate very technical bits and simple plays, just because it serves the song.
