Dave Brock resurrects the "Dr Technical" alias which he had previously used for production of the band's 1972 hit single "Silver Machine".

"The Phenomenon of Luminosity" features a sample of John Glenn on the Friendship Seven spacecraft during the Mercury-Atlas 6 mission on 20 February 1962.

An alternative version of "Experiment With Destiny" had appeared on the preceding year's Sonic Attack album as "Virgin of the World".

Alternative versions of "Some People Never Die" appear on Spacebrock and the Dave Brock solo album Earthed to the Ground (as "Assassination").

The CD bonus tracks on the 1994 Griffin release were recorded in the 1990s and seem at odds with the overall feel of the album, and they were placed in the middle of a resequenced side 2 by Dave Brock, disrupting the flow of the album, for example the rowing that linked "Some People Never Die" with "Light Specific Data" now has 5 tracks in between.
