The thing about NB is that they surfaced in 2003 for most people, although I recognize they'd been around for a while before that. I remember when Nate came on to the forum talking about some Transylvanian band and I actually laughed at him about Dracula or something.
Anyway, so 2003 was like the "year of Negura Bunget" because they released 'N Crugu Bradului, and simultaneously, people went out looking for their back catalogue. That's why it might have seemed like they were getting lots of hype because it was all concentrated around one timeframe.
If you think about it, comparitively speaking, we barely talked about NB in 2004.
I wonder how a masterpiece is discovered anyway? Is it something that becomes recognized immediately after its release, or does it take years for people to appreciate and recognize the genius? You never know, in a few years, everyone might rank "Sala Molksa" as their magnum opus....
