Though this might be of interest for this crowd.
My improv-drone-noiserock-doom-band, Old Believers, released an album yesterday. It is available on all streaming-platforms and on cassette(through bandcamp).
I play the cello(through pedals and loud amps), so does the trumpet player.
The album was recorded live, everyone in the same room, all improvised.
The guy who mastered the album album called it Tony Conrad meets Sunn O)) which I think describes it pretty well.
Hope you like it!
