I always thought it was funny that the black metal thread was started with a Thou recommendation. So I'm gonna go back to this thread's roots and recommend an album that is also not black metal. The mighty CONVERGE 'All We Love We Leave Behind' because I think everyone who likes extreme music should hear this record.
Converge has such a strong catalog. I love this one, and the latest one, The Dusk In Us, so much. First one I heard was No Heroes back when it came out, and since then, they have been my top 3 easily. Great, great fucking band.
And of course, Jane Doe..
