Clare Co Council has refused planning permission to an application to stage the Lisdoonvarna music festival after a gap of 20 years.
Aiken Promotions had planned a one-day concert at Lisdoonvarna on the 28th of June which was expected to attract 25,000 music fans.
It is understood the licence was refused after locals objected to the staging of the concert.
There is no right to appeal the decision.
