"Once in a Blue Mugic" comes to Dublin

A night of rocking out to great local bands for free? Sounds...mugical! It's all going down Friday night at the Button Factory thanks to "Mugic Happens", a no-charge monthly music offering.

Taking the stage are Hassle Merchants, Rhiannon & the Face Collectors, Cold Comfort, Elk, Pete & the Purehearts, Just No, and Bob Glynn.

The complimentary craic runs from 8pm-2:30am tomorrow night.

Listen to Hassle Merchants perform 'Tomorrow We'll Be Kings' at last October's "Where the Mugic Happens" below.
