Ok, somehow I missed hearing the best album of last year until just a couple days ago: Giles Corey - s/t. It's a solo project of one of the dudes in Have a Nice Life and Nahvalr, two projects some of you may be familiar with,, but as far as I'm concerned it's light-years beyond even those two projects (which have both produced some great music). This is some of the most emotionally wrenching music I've ever heard in any genre, and at the same time it manages to be pretty experimental, incorporating influences from a bunch of different genres (electronica, ambient, folk, alt-country, shoegaze, lo-fi, psychedelic rock, plus a subtle metal influence). I would not be surprised if this ends up in my top 50 albums ever, and possibly being my album of the decade.
That said there's still a bunch of other stuff I haven't listened to that could end up being contenders, but I'm having a hard time imagining anything topping this.
