It would seem that Michael Stearns experimented with quad as per the notes on his album "Sacred Site". One track called "Return" was recorded in 83 with the LYRA SOUND CONSTELLATION with a quadraphonic speaker array.
Sacred Site is on Hearts of Space records HS-11038-2
FWIW,
Micheal Stearns is the chap that released "Chronos" an Ambisonic UHJ surround soundtrack for the movie of the same name.
Unfortunately there is no way to conclude if the music was quad encoded via UHJ or any other matrix.
But it's interesting to note I thought.
