Cllr Anton Sampson is 'back on board'
He said: "I'm over the moon to be back and involved in something so close to my heart.
"I have always felt like a frustrated musician and working with the best talent in the area is the closest I'll get to really being part of such an exciting scene."
Cllr Sampson is working with the Cookhouse, who are hosting the event in their car park, High Street, Prestatyn.
"Prestatyn Rocks is an amazing platform for bands to get their music out there to a wider audience," he added.
There will also be an acoustic area at event.
Prestatyn Rocks is free. There will be collection buckets on the day with all money going to Rhyl RNLI.
