How good are Slayer???
Saw them in Cardiff a month ago, and they'll be my #shirtonsunday in a couple of weeks. I was never a big fan until a few years ago when I saw them as they shared a bill with Anthrax (nothing new there). Shame they're retiring, but I guess it's pretty hot up there.
We found the whole evening pretty intense so I hope you got some catharsis out of your night, if the preceding days were as you describe.
