The series of concerts which included dates in Tramore, Cork, Limerick, Kilkenny have been cancelled.
Gavin James, Aslan and Hermitage Green were among those due to perform.
Those who bought tickets would have watched the concerts from within their cars.
Local Organiser Mark Dunne admits that the cancellation has left them "shattered."
"Not only just for the hundreds of hours of planning we put in, but the whole ethos of the event was to get our providers, suppliers, artists, and security back to work, it's a very beleaguered industry at the moment," he said.
"We tried to do something good for the industry and unfortunately the powers that be have just come down and slammed the door shut."
