Waterford acts Backroad Smokers Club, Alex Gough and Carrie Baxter have all been newly added to the All Together Now line-up.
The festival of music, arts and comedy returns to Curraghmore after a three year absence, for the August Bank Holiday weekend, July 29th to 31st.
Nick Cave, Groove Armada, Underworld and Sinead O'Connor are among the big name acts for ATN, unveiled by organisers a number of months ago.
Following on from the initial headliner announcement, promotors today revealed over 50 more performers, a comedy line up and festival experiences.
As well as the vast array of music, comedians such as David O'Doherty, Jason Byrne, Ardal O'Hanlon and Blindboy Boatclub will perform at the Waterford venue, and the popular Arcardia Spectacular stage also makes a comeback.
