I think the next metal genre should have complex rhythms and intense atmosphere, with clean vocals and postmodern, abstract lyrical themes. It would also be nice if there was a hang drum involved.
I dunno, maybe it's already a genre but I'd like to see more dark metal - that melodic, highly atmospheric sound that's dark and sad without really trying to be evil and not cheesy like goth.
Welcome to the world of Bethlehem.
Actually dark metal is more commonly used to refer to the Agalloch-esque bands like Woods of Ypres and October Falls than to the DSBM bands like Bethlehem. Bethlehem just coined the phrase.
