Mocrac will play on August 25 with Tasc from Waterford in support.
Mocrac are currently putting the finishing touches to the revamp on their debut album, which was self-released last year and to be released by Reekus in autumn.
On Saturday 26, David Hopkins returns home to Dublin, and plays Tonic ahead of his performance at the Electric Picnic. In tow are the hotly-tipped The Radio.
Entry for both shows are the most reasonable price of free.
