Initiation (Course of Empire) Easter Egg - Embedded Tracks

Course of Empire's album Initiation has a few areas on the album where embedded music can be heard when played in mono or L+R mode. Stumbled upon this when working at a music store back in the mid 90's and we accidently hit a switch so it was being played in L+R mode. Static dropped away and a tune under the static could easily be heard. Without changing the mode it only sounds like static.

Quoting a reviewer here is more information:
"The ingenious and technologically adept may find a couple of buried tracks, courtesy of producer and mixer David Castell. One is disguised as the non music-related information before the first song. Another is embedded within heavy doses of white noise feedback later in the album, and can sometimes be distinguished when played in mono." Norm Elrod, All Music Guide
