I don't know if it would make much sense to make the library album quadrophonic. The albums were intended to work like catalogues of music. So you listened through the tracks until you found the track you were looking for, then you ordered the master reel to be used in your production. Of course some quadrophonic tracks could have made a better impression, but i suppose not so many would have listened to them with the right equipment. And if they did and like dit, it wouldn't be quadrophonic in the production anymore. Correct me if I'm wrong!
But then again I'm sure there must be some library tracks reissued on some quadrophonic moody albums for home listening.
I wonder where the quadrophonic sound effects would have been used, maybe in theatre plays?
