I've seen it all before... Trivium LOOKS awsome on stage, but their songs are ALOT better on record. I heard them as warm up band for maiden in 2006.
Also I heard slipknot and COB a few months ago in Oslo
Awsome.
You should check the setlist, they play the same songs all the way this year..
I also went backstage with slipknot and interviewd them for www.abcnyheter.no Awsome!
Machinehead played to at that concert, their music is all the same... to simular, but they were GOZI live!
