One thing, that just came to me. I's not about what 'rocks' Poland, because most of these bands are quite forgotten - but I really LOVE Polish doom bands from late 90's.
Nowadays, everyone plays doom metal just as they do in USA, or Western Europe. It's fine, but it's not fresh. Then, music still had kind of "garage spirit", underground sound from behind the Iron Curtain - some of you guys, who live too in post-soviet countries should know what I mean. And besides - 90's brought doom metal, gothic metal, and fashion to sound darker and more pathetic. And even if it sometimes was kinda dauby - it still sounds awesome and fresh.
