Another one, getting in to the Warner Bros. side of things is Mike Butcher did the quad mix of Black Sabbath's 'Paranoid'.
What's interesting is the clipping below from Billboard Dec 10th 1973 says that Butcher went to Morgan studios Brussels to mix 'the new quadraphonic Black Sabbath album'. It's possible that he was just going to mix Paranoid, but if that's not the case it means he was doing a quad mix of Sabbath Bloody Sabbath, the stereo mix of which was released in December 1973.
Maybe it's wishful thinking (or hoping) on my part, but maybe Warners put out the quad mix of Paranoid and sales didn't meet expectations, so they didn't bother putting out the quad mixes they had in the can of the albums subsquent to that. As we know, Sabotage (the album that followed Sabbath Bloody Sabbath) was slated for quad release and even had a catalog number so it's no stretch to think there's a shelved mix of Sabbath Bloody Sabbath. Look at Jethro Tull, another British Warner Bros. artist - they had a bunch of shelved quad mixes that have definitely turned out to be real because they've been released on the recent deluxe editions. Some of them were known about or had catalog numbers assigned (Minstrel In The Gallery), and others were a total surprise (A Passion Play, and apparently Too Old To Rock & Roll as well) so I just hope the same is the case with Sabbath and the mixes come to light someday.
