Lately, all I can listen to is the surprise release (announced only two weeks prior; their first release in over a decade) from Montreal post-rock legends, Godspeed You! Black Emperor. Dark and brooding, tons of guitar feedback, perfect for an autumn apocalypse.
Below is the album, Allelujah! Don't Bend! Ascend! in full (its proper release comes via the Montreal-based label, Constellation Records). And here is the only interview they've done to promote the album, which comes courtesy of The Guardian. For anyone who's more than mildly interested, it's definitely worth a read.
