Ages: 29, 29, 29, and 51 (“Matt’s the old guy.’’)

Hometown: Portland, Maine

Think of: Mumford & Sons meet the Avett Brothers with a twist of bluegrass. Old Crow Medicine Show with three-part harmonies. The Band for millennials.

What caught our eye: The Maine-grown, foot-stompin’ holler-folk quartet create the type of music for which festivals are made. In 2011, three twentysomething childhood friends — Max Davis, Sean McCarthy, and Griffin Sherry — became the Ghost of Paul Revere when they teamed up with musician Matt Young. The quartet has since shared the stage with Brown Bird, Spirit Family Reunion, Will Dailey, and the Avett Brothers among others, bringing a charge of energy to every show. The group’s first full-length album, “Believe’’ (2014), hit the Billboard Northeast chart, and since winning a 2014 New England Music Award and making their Newport Folk debut last year, they’ve garnered a serious following of loyal devotees.

Light-bulb moments: Davis, McCarthy, and Sherry grew up singing in chorus and playing middle school band together — but “didn’t grow up in folk or bluegrass traditions,’’ Sherry said.

So his first light-bulb moment was discovering bluegrass — and Dylan: “When I was 16, I bought an acoustic guitar and started writing my own music. That brought me to discovering Bob Dylan’s entire catalog, and the Band, and this group called Iron Horse that did a cover record of Modest Mouse songs in bluegrass, which I fell in love with. Then I found Bill Monroe, and all the people who came as a second renaissance after ‘O Brother Where Art Thou?’ ’’

The second: “The idea of Ghost of Paul Revere came to me in a dream, and I couldn’t shake it. So when I started performing solo, I was Griffin Sherry and the Ghost of Paul Revere. . . . When we formed at a bar five years ago, we became the Ghost of Paul Revere. I liked it because it implies that we’re playing with a certain message. For us, the message is community — our music has an old field-holler energy to it, something you can only get in a room full of people. And Longfellow was from Portland.’’

Biggest thrill: After winning an emerging artist contest run by Converse Rubber Tracks Studio and Newport Folk Fest last summer, the Ghost earned both fest stage time and studio recording time in Boston.

“Just meeting some of the people we met at Newport Folk — James Taylor, the Lone Bellow, Jason Isbell, Bela Fleck — it was like, ‘I think we’re doing this right.’ ’’

Biggest surprise: “The overwhelming support that we’ve found outside Maine. We’ll get messages from people in California or Colorado, Texas, people in the UK, Sweden. . . . And also, that there are four people with Ghost of Paul Revere tattoos. Someone got an outline of the state of Maine with the lyrics to [the band’s song] ‘San Antone.’ . . . That someone would want to have your lyrics on their body for their entire life is the most humbling thing.’’

Inspired by: Tall Heights, the Ballroom Thieves, David Rawlings, Ryan Adams, Punch Brothers.

Aspires to: “Make music a career, keep playing as a band, and better ourselves as musicians and writers.’’

For good luck: “We huddle up and sing Paul Simon. ‘Loves Me Like a Rock.’ ’’

What people should know: “There’s a good chance they can find a show — we do 200 a year. Expect it to be high energy. We bleed and sweat.’’

Coming soon: At the Narrows Festival for the Arts in Fall River, 4 p.m. Sept. 11. At Me & Thee Coffeehouse, Marblehead, Sept. 23, 8 p.m. www.ghostofpaulrevere.com
