Beatyard looks like it's going to be even bigger and better this year.
The festival is taking place again over the August bank holiday weekend in Dun Laoghaire.
People love it because of its small size and handy location but also because of its great food stalls and flea market.
Mark Ronson will headline the main stage on Saturday while Air will close the festival on Sunday evening.
Candi Staton, Kila, Toots and the Maytals and Choice Music Prize winners Rusangano will also be performing.
