Looks documentary-ish to me, like it probably worked very well within a series (supported the album cover from what you say) but standing alone not an earth-shaker. Maybe it's the album-oriented square format restricting a casual scene, maybe the Great Leibowitz needed to rush off to another celebrity gig, I don't know, to me this is just a straightforward historical record, taken in passing.

PS- Not that there is anything wrong with square, or taking in passing
