I didn't get a whole lot of music from 2012 in 2012. Here are some of the music things I dug.
Mumblin' Deaf Ro - Dictionary Crimes (above)
Baroness - Yellow and Green
The Glimmermen - Satellite People (EP)
The Spook Of The Thirteenth Lock - The Brutal Here And Now
Mudbitch - Ready, Aim, Fire (EP)
Just noticed that 4 out of 5 of those are Irish. Glad that that was totally accidental. Most of the links here bring you to a bandcamp site. A brilliant way to buy music directly from the bands.
