Running since 2003, Hard Working Class Heroes (HWCH) kicks off Thursday 28th September all across Dublin city's quirky places and bigger spaces.
All to showcase 50 of Ireland's most exciting new acts to fans and especially to international agents, festival bookers, record labels, publishers, managers, event curators and journalists from around the world.
To tell us more about it, HWCH organiser Angela Dorgan popped in for a chat with Louise on Lost in Music.
One of the breakout acts from HWCH is Dublin band Otherkin, who release their debut album OK on Friday 29th September.
From the HWCH stages, they've gone on to open for Guns 'N' Roses at Slane Castle and tour with The Dead Kennddy's this summer.
And they'll be busy this autumn with a European and UK tour. Finishing in Ireland, playing The Button Factory on December 15th and the Roisin Dubh in Galway on December 16th.
