I've always wanted to see MDB, got ALL their albums but never been able to make it to any of their shows, Carcass and ND will be great and I'll be interested to see what Sigh do live, seeing as their albums are fucking insane!
ND should be great, interesting to see what material Carcass play and if it's the cleaner sounding stuff as opposed to the early material. Imagine Sigh would be an experience
Yes, this will be really good. My Dying Bride played an absolutely EXCELLENT set at Hellfest, a couple of classic gems and the pick of the litter of the newer stuff (I'm not the biggest fan of all of their newer albums to be honest).
I'd definitely advise tickets to be bought sooner rather than later..
