The Barra MacNeils, who will perform at Medford’s Chevalier Theater on March 7, have forged a hugely successful career of nearly three decades playing Celtic music, including that of their native Cape Breton.

Legendary Celtic music performers The Barra MacNeils, who have traveled far and wide for nearly three decades to present music from their native Cape Breton, as well as Ireland and Scotland, will journey next month to Greater Boston, where they will present a concert on March 7 at 7 p.m. in the historic Chevalier Theatre in Medford.

The event commemorates the 75th anniversary of the theatre’s dedication in memory of pioneering Medford aviator Godfrey Chevalier, the first American to land an airplane on a moving ship. The Chevalier has a Greek Revival style exterior with Art Deco interior details, including a double elliptical ceiling that provides near perfect acoustics, and over the years it has hosted local and touring musical and theatrical shows, and civic, school, and performing arts events.

Now the Chevalier will add another chapter to its distinguished history by serving as a venue for the Barra MacNeils, whose performances are noted for featuring multiple lead vocalists, songs in English and Gaelic, entrancing harmonies, numerous acoustic, stringed, percussion and wind instruments, and step dancing.

If you were a fellow in the prime of life back about, oh, a couple of hundred years or so in the British Isles, a press gang was the last thing you wanted to meet. Listen to a few traditional songs from the period (“Arthur McBride,” “William Taylor,” “All Things Are Quite Silent”) and you’ll know that press gangs constituted an altogether nasty form of military recruitment, notorious for using bribery, deception, or brute force to compel young men into serving in the Royal Navy.

But today, if you meet a Portland, Me.-based trio calling itself The Press Gang, there’s no need to fear, especially if you’re a fan of Irish music. That’s because the combo of Alden Robinson (fiddle), Chris “Junior” Stevens (accordion, concertina), and recent Boston-area arrival Owen Marshall (guitar, bouzouki, harmonium, banjo) has established itself as one of the more compelling New England trad bands to emerge in the past several years. Their love of and respect for tradition is apparent, as is the sheer ebullience with which they play, and the overall joviality they bring to the whole enterprise, whether in their sometimes adventurous approach to material and arrangements, or their good-natured, even self-deprecating sense of humor.
