Terry, listened today to a CD I totally could not remember, which was
Appearance of Nothing - Wasted time ( album from 2008, Swiss band)
and to answer your question it was a long-track called "The Science of light" 3 parts 14:37 in total
since that is nowhere to be found on the net this will give you an idea:
Appearance of Nothing - Lies of a Memory
