Already heard (with ratings and reviews)
The below list is ratings given in a professional sense, and my personal top 2011 albums list may have some variations. Ratings are given based on the standards I hold for release of that genre and if I'm familiar with the artist already, the standard that I hold that artist to.
As such although this list is ranked from the higher scores going down, that DOES NOT always mean that a death metal album scored at 8.0 is a better and more enjoyable release than a folk metal album scored at 7.5, or whatever. I'll post a personal list of albums at the end of the year.
9.5 - 10.0 - Masterpiece/Classic Album
Anubis Gate - Anubis Gate - (Review) - 10.0
Teodor Tuff - Soliloquy - (Review) - 10.0
Factory of Dreams - Melotronical - (Review) - 10.0
Dark Forest - Dawn of Infinity - (Review) - 9.9
Ancient Bards - Soulless Child - (Review) - 9.8
