LEWISTON — Since its inception in 1996, Solas has been proclaimed the most popular, influential and exciting Celtic band to emerge from the United States. The Irish Echo ranked the quartet among the “most exciting bands anywhere in the world.”

Since then, the praise has only grown louder for the group that will perform at 7 p.m. Sunday, Aug. 16, at the Franco-American Heritage Center in partnership with New England Celtic Arts.

It has performed at major Celtic and folk festivals as well as at the Telluride Bluegrass Festival and at the chamber music summer series at Steamboat Springs, Colo. It has also played at Symphony Hall; Wolf Trap; the Ford Amphitheater; Queens Hall in Edinburgh, Scotland; and at the legendary Bottom Line folk club as well as Town Hall and Symphony Space in New York City.

Solas’ sound is anchored by founders Seamus Egan, who plays flute, tenor banjo, mandolin, whistle, guitar and bodhran; and fiddler Winifred Horan. Mick McAuley from Kilkenny plays accordion and concertina; and Eamon McElholm from Tyrone plays guitar and keyboards.

The internationally acclaimed supergroup has captured the hearts and ears of Irish music fans worldwide with its blend of Celtic traditional, folk and country melodies, bluesy sometimes jazz-inspired improvisations and global rhythms. The group’s latest release is a live CD and DVD called “Reunion,” which celebrates the band’s 10th anniversary.

Tickets are $20 in advance, $25 at the door. Call 689-2000 or purchase online at francoamericanheritage.org. Doors open at 6:30 p.m.
