I don't think I've heard any albums from 2011 yet... 
In all for realz, I haven't heard much... based on what's in my Discogs collection, most of it is noise **beast**, and some of it is stuff that was re-issued. Out of that, I guess these were the 10 best, in no particular order, because that requires too much brain power:
Raspberry Bulbs - Nature Tries Again, 2011 cassette re-issue
Fækal Omsorg/Fatal Position split
Ruins - Chambers Of Perversion, 2011 CD re-issue
V/A: Silence = Death comp. I even liked the Xiu Xiu contribution, which is saying something
V/A: What The Hell Is A Jiggawatt?!? comp.
Hedorah/Marlee Matlin split (really good, even if I don't much care for Family Guy samples, as heard throughout MM's half)
Facialmess - Total Liberation netrelease
Young Egypt/The Uh... - Central Ave., split
Pine Hill Haints - The Evening Star
V/A - Southern Noise Comp, because I need to pimp it in a vain, fruitless attempt to sell some copies to you guys and make a little monay... But I actually am very pleased with the quality of the submissions... I really do think it's good! I accept PayPal, MO's and well-concealed cash! 
And an honorable mention, left off the list only because I can't confirm that it came out this year, but this is the year I heard it, and it's really good:
Pissdeads/THC Eradicus split on Trichome Noise Recordings
Also, the Smiths Complete box that I can't **beast** afford!!!
Check my wantlist! I am not looking to make trades from my collection, but I am happy to swap tapes of anything in my collection for (almost) anything in my wantlist. Get in touch!
