There was a day when i worked for soundPower (Toronto) I was the music programmer for background music for local pubs in Toronto. This was the 70's there was no web or satellite.  We replaced our open reel tape records with a loop tape system.  This is a 2016 recreation of what our jazz tapes sounded like .I was a dj at BRANDY's at this time period.
