What is the best concert you have ever been?

Used to be in the metallica club and went to one of their small shows when st anger was released and except for one or two st anger songs, they played all old stuff.

I'm into all the classic swedish melodeth bands and there were a ton of really good shows in the 2000s. Perhaps one of ny favorites of those was when Dark tranquillity, Insomnium, and swallow the sun toured together. I think There was a 4th swedish band on that tour but cant remember who. Maybe soilwork? Or maybe it was soilwork and not DT.

I saw DT and soilwork a zillion times but only saw insomnium and swallow the sun that once.

First time i saw Devin Townsend was pretty special too.
