There’s a new Irish festival in town: Tunes on the Charles. Information is still trickling in. The Instagram account has only eight posts. Media inquiries have so far gone unanswered. But you know the drill. This is a traditional Irish music festival in a metro area that loves its Irish heritage. Concerts, classes and good old-fashioned craic is on the menu at “on the nose” locations such as The Druid, The Burren, McCarthy’s, An Sibin and wild card Lilypad. The new festival doesn’t have the decadeslong roots of local traditions such as the annual Boston Celtic Music Festival. But with solid institutional support from Irish cultural organizations on both sides of the Atlantic, this newcomer should be ready to hit the ground running.
