Yeah, I've heard it and it's the same flavour of fake as
Cosmic Slop - about half the tracks are the stereo mix in the front, with a clang-clang echo chamber version of same in the rear speakers, and then the other half are the stereo mix in the front left and rear left, with the echo chamber version in the front right and rear right.
Ecstacy very rarely comes up for auction, I've probably only seen it once or twice in my 20+ years of collecting. I've seen
Cosmic Slop a little bit more, maybe 4 or 5, and the last couple have gone for stupid money, like $300 per tape. I feel bad for the people who pay that kind of money for a tape with a fake mix, but I guess by the same token, if you can afford to spend that kind of money on a 40 year old 8-track tape, you're probably well off enough to weather the disappointment. Presumably the reason these two tapes are so scarce is because no one who bought one back in the day reccomended it to a friend, given how lame the mix is.
As for
Skin Tight and
Contradiction, as I mentioned in the
Mercury/Vertigo/Phillips discography/history thread that I did, I don't think either of these Q8's were released. The Mercury Q8s are relatively scarce compared to other major label releases, but the BTO tapes show up fairly regularly on eBay, and the two other Ohio Players Q8s (
Fire and
Honey) do occasionally as well. I feel like if either of these were issued, we'd have seen evidence of at least one in the 40+ years since. Labels weren't in the business of making things and not distributing them, and these weren't obscurities either - both of these albums hit #1 on the R&B charts and nearly made it into the Top 10 of the pop charts.
