Does anybody know 'Before The Dawn'? It's a death metal band from Finland... One of the greatest I've heard in a long time.
Powerful chords, very melodic, great singers...
There is also Rootwater from Poland. (mix of In Flames, System Of A Down and Sepultura with folk influences).
I've been savoring a lot of symphonic and folk metal at the moment:
In Silentio Noctis
Rhapsody of Fire
Ram Zet (one of my faves, one of the few extreme metal bands doing something different)
I could go on for ages, metal is such a varying genre of music that it's easy to find many bands that are highly enjoyable.
