There is no rpm information on the record or sleeve. The track durations as printed on the cover are valid if played at 45rpm. But I believe it should be played at 33rpm (resulting in the durations 16:30 and 16:51).I bother to submit this at all, because it isn't a studio recording where you could argue about the artist's intentions, but a live recording. And by listening to my record, I'm utterly convinced that 33rpm reproduces the original event.There's a possibility to compare it (see edit history). The track durations there are as printed on the label. Compare by playing with 75% speed (mplayer does an acceptable job for me, I haven't found a reasonable recoder, yet).I'm adding this as comment because other record owners might want to confirm or negate my suggestion.

both tempi are right!https://vladislavdelay.bandcamp.com/album/kind-of-blue-epfor example "the black album" from boyd rice you can play on three different speed.and if you are funny you can play this record backwards too :)

Stumbled across this obscure, stickered, white sleeved record in Glasgow, and it threw me across the room-my first exposure to Vladislav Delay's now immense body of work. Along with his work on Sigma Editions, this is the best music he ever made.
