no particular order:
Napalm Death - Time waits for No Slave
Hits the spot for catchy riffage and grindy simple death, consistent.
Daath - The Concealers
Another pretty 'basic' but catchy album yet not too easily categorized, great guitar work too.
Animals as Leaders - S/T
3 of my faves this year are instrumental, some genius guitar work and interesting genre blending here.
Augury - Fragmentary Evidence
Doesn't quite edge out the debut for me but awesome album, unique style and great musicians.
Exivious - Exivious
Another instrumental, along the lines of Cynic but I liked it more then the new one, more focused on the fusion technical side of things.
Katatonia - Night is the New Day
Another great album from these guys, lots of dynamics even amongst the doom. Drew me in more then the last album although that was also excellent.
Nile - Those Whom the Gods Detest
A return to the epic sound that made Annihilation such a great album, along with some more variation in the tempo to keep things interesting.
Revocation - Existence is Futile
Deathy thrash with some tech leanings, reminds me of a modern version of Coroner with a bit of Voivod at times, excellent newish band.
Dysrhytmia - Psychic Maps
Yet another instrumental, this one is more hard rock but some very interesting ideas and progressions, with a dirty and natural production that suits the music perfectly.
The Red Chord - Fed Through The Teeth Machine
Killer riffs and songwriting make this stand out from the pack for me, technical and brutal but still dynamic enough to remain listenable for the entire album.
Other good ones:
Dream Theater, Bloodbath, Obscura, the Faceless, Gorod, Lost Soul, AIC, Behemoth, Hypocrisy, Redemption, BTBAM, Chimaira.
Dissapointments:
Devin Townsend, 3.
