One of my favourite record labels (if not my number 1 - I have the t-shirt after all), specialists in left-field experimental black/doom/drone metal Aurora Borealis have put out a free downloadable mixtape. It's over 30 minutes of epic, intense and visceral sounds from their most recent releases, the tracklist includes Rye Wolves, Burial Hex, Sylvester Anfang II, Heavy Winged, Wormsblood and more.
Pretty awesome stuff.
Here's the link for you.
I wrote more on my blog. Only a bit more mind.
