Monique Froese's rear cover artwork collage includes an image of a man's lower face, apparently a photograph of a sculpture, which looks extremely like the death-mask of classical composer Ludwig van Beethoven.

The closing section of the title track also uses La Folia, Op.5, No.12 a classical piece of music by Arcangelo Corelli in 1700.

A heavily remixed version was played live in 2003, and later released as "Meta Morph Magic" on the DM 4 album.

A 2019 CD version, re-mastered from the original master tapes, includes a 1979 Christopher Franke solo recording, 'Chimes and Chains', as a bonus track.
