Deathspell Omega... either you find them groundbreaking or boring, but if someone tells me they're mediocre, I know there's no point discussing further. I can't wait to know where they're headed with the next album.
And it's also kinda cool to see the first wave of allegedly DsO-influenced bands bursting forth, like Hexenkreis, Drastus, Glorior Belli, all very good.
