“It’s easy to halve the potato where there’s love.” This Irish idiom aptly describes the generosity of veteran musician and folklorist Mick Moloney. As front person for traditional Irish-music band Green Fields of America, he has showcased and nurtured the talents of more than 70 musicians and dancers over the past 40 years, including fiddler Eileen Ivers and dancer Michael Flatley. The current sextet fills the stage with voice, banjo, mandolin, guitar, fiddle, button accordion, keyboards, spoons and Irish dance. Young Tradition Vermont presents the ensemble as part of the 24th annual Burlington Irish Heritage Festival, a 16-day celebration of Irish arts and history.
