Sorry, does not exist on LP. They were from the town Yartsevo, Smolensk Oblast. The recording was released on reel tape, if I remember right.
Edit: Just saw that it says were they are from in the clip you posted.
Haz looks amazing but when I listened to it at Dan's place some years ago it sounded pretty bad. Not in the same league as Resistencia, Arkangel... But still a great collector's piece! Congratulations!
