Album length remixes / edits?

Not quite what you're looking for, but the headshop boys did mixed edits of tracks from Graceland and and another of tracks centered (but not exclusively) on Rumours. Nguzunugu or whatever did a mix of remixes of "moments in love."

By "tracks" in that second one I also mean edits. So like six or seven edits make up each mix.

It's funny that edit in dance music almost always means making a song longer.

The Orcutt/Hoyos duo was also responsible for a previous posthumous release, Let's Build a Pussy, which emerged in a tiny edition not long after the band's 1997 demise. As with One Plus One, Orcutt provides the guiding hand here, but in a much odder way. He isolates a single second of Hoyos' singing from the song "Ice Cream Man", then stretches it into an hour-plus of abstract sound interrupted only by the ends of four vinyl sides. (Orcutt is credited with "Mouse," i.e., the computer kind, while Hoyos' contribution is listed as "Mouth.")

This might not count, but there's an Autechre track that could fit in here; I'm presuming the 58 minutes of Perlence Subrange 6-36 has some kind of remix or similar relationship to Perlence Subrange 3, and the other tracks prefixed Perlence on the same ep. However, it is Autechre...

It's just a really, really slowed down version of one of the loops for 58 minutes. I've listened to it a couple times (it is very relaxing) and there are a few moments of "wait, was that there before?" but I think it's kind of stretching what "album-length" ought to mean

I got the idea to make a version of The Cure's Six Different Ways, in six different ways. Cover, disco version, dub version, etc. Mixed together like a Boredoms ep.
