I ended up going. The venue was awesome, small little sweaty club, would have been great to see Evile there.
Zonaria weren't that great, and I generally didn't enjoy it for most of the set. Their singer seemed like he was trying to be a mix between Alexi Laiho and Robb Flynn except he couldn't solo or sing that great. Plus they were wearing armor haha, I guess they thought it would make them look metulz.
Bezerker...my God they were bad (imo). It was probably the worst band I've ever seen live and I've seen a fair few bad ones. I hate grindcore even more than I did before now.
Satyricon isn't my cup of tea music wise, I've always disliked black metal but to be honest they really weren't all that bad. They got the crowd going and knew how to put on a good show.
