I think I've said this three times this year already, but: show of the year!
Kreator and Overkill are probably my two favourite thrash bands aside from Metallica and Slayer, and Warbringer is easily the best new thrash band around. Add to this the fact that thrash is the best subgenre of metal, and you have one of the greatest lineups I've ever seen!
11/7 - Artillery/Onslaught
11/27 - DTA/Obituary/Massacre
