Back in the 80s some tours came through the DFW (Dallas Fort Worth) area that were carrying an EV MT series sound system. One production that comes to mind was the Prince Love Sexy tour of 1988 / 1989 that stopped at Reunion Arena in Dallas Texas on November 29, 1988. I was 16 and got to work for IA 127 on the stage crew. I didn’t get to see the entire show but caught the end including the encores. I honestly don’t remember how it sounded but the sound system was an EV MT rig.
