The second of the four unknown songs to be identified on July 23rd., "Power Plant," is also the first of two to be written by Rick DiFonzo. Rick DiFonzo was a member of The Bleeding Heart Band that backed Roger Waters around 1990, and he's also associated with the BRg production music company. Power Plant, as well as the song I'll post the ID for tomorrow, comes from the BRg library. This library is hosted on the Manhattan Music website. Unfortunately, Manhattan doesn't appear to show album release dates anywhere on their streaming service. I also couldn't find these albums on Discogs, so the year that Power Plant was released will remain murky for now. Again, thanks to Godzfire for getting this track ID'd.
