I found these two Black Sabbath LPs when thrifting:
The Vol. 4 is a (somewhat shady) pressing from the USSR from 1990. I didn't have any expectations on the pressing quality, I just thought it'd be a novelty item. The Sabbath Bloody Sabbath is a regular, Western pressing.
Here's my record collection (Discogs), for anyone interested.
This post was retroactively compiled on 2024-01-19 from a photo in my photo library. The USSR vinyl sounds just as bad as you would imagine.
