Some great albums on this list and some more I will need to check out. Totally missed that Incantation had a new album out.
Despite that I think there were at least several other releases this year that probably deserved to be on this list more than some of their choices.
04/05 - Kataklysm, Aborted
04/08 - Carcass, Gorguts, TBDM
04/23 - Behemoth
04/24 - Nile
