Dermot Kennedy’s global Irish music festival comes to Boston for a two-day turn on March 18-19. The Co. Dublin native’s “emerging artist showcase” at the Brighton Music Hall on March 18 is already sold out. But there are some seats still available for his headlining show the next night at TD Garden. The 32-year-old singer and songwriter will launch the music fest a few days before in Sydney, Australia.

Kennedy sat with Boston Irish last fall to talk about the inaugural festival, which he sees as a re-invention of the St. Patrick’s Day celebrations that he has seen elsewhere. The name “Misneach,” (pronounced mish-nyach) means “courage.”

“I think in Ireland, we’re so proud of our music and our heritage and our culture,” he said, name-checking artists like Van Morrison, Sinead O’Connor, and Thin Lizzy. “And so just on that celebration around St. Patrick Day, I wanted to make sure that’s what we’re celebrating. I think there’s so many artists at home that people might not be aware of that are so talented and so special and just deserve to be heard. So, it’s a lovely thing to put together, honestly.”

He added: “We’re so proud of that culture that still exists and there’s still so much excitement in Irish music, but it just seems like a good opportunity to celebrate it. And, even if Boston and Sydney is just the beginning, like to have a global celebration of Irish music and culture— there’s a big opportunity there.”

Tickets for the March 19 TD Garden concert featuring Dermot Kennedy, The Swell Season, Ye Vagabonds, and Nell Mesca start at $49.50. Go to misneachfestival.com to buy tickets.
