By the way, it seems very strange to me that many people here hail post-LP era of PERGAMENT. It's good, but it just can't beat up the cult of Vruća Linija LP. That post-LP stuff is maybe a little bit stronger in technical terms, but unfortunately is more predictable too.
Unfortunately, the most charming part of PERGAMENT were their awesome lyrics in serbian, which weren't translated well in later stuff. For almost all metalheads in ex-Yugoslavia the LP is essential and the rest is just as some additional good or something.
