I discovered a new (to me) band on bandcamp. Like them a lot, from what I heard so far.
Hypnodrone Ensemble
It's two guitarists and three drummers playing drony instrumental post/space/kraut/psych-rock, on some albums there may be other people playing.
The guitarists you might know already, one is the guy that names himself Thisquitarmy, the other is Aidan Baker.
Many of their albums are digitally for sale on bandcamp as Name Your Price, if not on their own site then on another mirror label.
