Opeth - "Nice guy metal" it may be, but it always helps me to enjoy a show when all the band members are smiling and the frontman has a great, positive attitude (at least he did 4 years ago when I saw em). Maybe it's just me but I found shows like Suffocation were kind of spoiled when the frontman was talking about killing me if I dated his daughter. Just play your music guys and keep your lame comments.
Kreator - Again, energy was enormous, and the song introductions were just so over the top and THRASH you had to laugh. Any band taking themselves that seriously should be commended. The soloing was insane and the huge crowd and the fact it was their first tour here ever helped to create an unforgettable atmosphere
Dismember - FUN FUN FUN. They played for only about 60 people and put in a massive performance nonetheless. Everyone in the band was smiling at us, making horns including the drummer and with the stage at ground level, it turned out to be a really personal performance which helped the "old-school" atmosphere.
(If I had to choose 4, i'd pick Soilwork - Yeah, it's hard to believe, but they were energetic as hell, and they really ripped up the stage, even with their newer songs.)
