As mentioned by many Nile, Opeth, and Primordial are up there, although I find Primordial to be a bit overrated, but still good.
Origin - Echoes of Decimation was pretty good I thought. I liked it better than III, but after hearing how nice the production on Annihilation of the Wicked was, it sort of lessened my opinion of Echoes.
The Karl Sanders album and Drudkh were both disappointing, but not really surprising.
Octavarium was derivative and bad.
Porcupine Tree - Deadwing is right about on par with previous efforts, so it's pretty good.
