I have no idea if this was a finished product or if it really (still) exists but multi channel is much more fashionable now (hint).Incantations (quadrophonic mix)
The album was originally conceived and recorded in Quadrophonic sound, and a mix of the album in this format was prepared. As the quadrophonic format had gone out of fashion by 1978, a stereo mix was made by Philip Newell. The original quadrophonic mix still exists, however.
