If the word “annual” was an uncertain speculation of the first annual Belfast Free Range Music Festival, those uncertainties were put to rest the morning of April 24, as the daylong multi-venue music extravaganza sold the last of its 450 general admission passes.

Two hundred fifty all-access passes, which included entry to the headlining act, Jazz Mandolin Project, at the American Legion Hall, had sold out the night before, and according to festival organizers, at least 200 people were turned away on the day of the show.

Festival organizer Meg Fournier said she and others who worked on the event were still tallying attendance numbers and the $5 entrance fees for individual shows, of which Fournier said there were “quite a few. A lot more than we expected.”

Twenty-seven acts performed at six venues around downtown Belfast. They ranged from solo acoustic acts — many of which, including The Fofers, Lady Lamb the Beekeeper, Travis Cyr and the Strings of Calamity and Unbunny, performed under monikers that suggested more than one player — to fully amplified bands. While many of the bands were from Maine, several of the performers hailed from as far away as Washington, D.C., and San Francisco.

Fournier had heard there was a musician from one of the bands who was stuck in Colorado — she wasn’t sure — but everyone else showed up.

“It went surprisingly smoothly for a first-year event,” she said. “We’re really impressed with how things went. All the musicians were there on time. Any technical difficulties resolved themselves by the show start time.”

Main and High streets in downtown Belfast lived up to the “festival” billing as people circulated among the shows, soaking up the sunshine and mild temperatures, lingering outside the venues and setting out blankets on anything resembling a lawn. A number of musicians not appearing on the schedule busked on street corners.

“I think that was one of the most promising things [for future festivals], as people understand that we’re really open for street music,” said Colonial Theatre owner Mike Hurley, who was involved in organizing the festival. “The welcome mat is out to come on down and play.”

Hurley said he ran into people at the festival from as far away as Austin, Texas, and many from other towns and cities in Maine.

“If anyone ran into the most trouble [getting into the festival], it was the local people who probably thought, ‘It’s not going to be a problem. I’ll just go down there and get a ticket,'” he said.

Hurley expressed gratitude to the sponsors of the event, particularly Bangor Savings Bank — a major contributor — and also to the bands, who performed for less money than they might have ordinarily.

And apparently they had a good time. Fournier said she has received many positive e-mails from performers since the event.

“A lot of the musicians hadn’t been to Belfast before, and they commented on the energy of the crowds,” Fournier said. “There were people of all ages, and dancing, and people were staying after the shows to talk to the musicians.”

The evening’s headliner, Jazz Mandolin Project, performed an hour-and-40-minute set at the American Legion Hall, featuring guest appearances by clarinetist and jazz whistler-extraordinaire Brad Terry, along with Colonel Bruce Hampton and Grant Green, who had performed earlier in the day.

Fournier said there would definitely be a second Free Range Music Festival next year, probably with more venues, possibly extended to multiple days. What she hopes to keep the same is the diversity of genres represented by the acts that appeared this year.

Hurley, too, was optimistic about future festivals.

“People don’t need a lot of reasons to come to Belfast,” he said. “People love Belfast. They love coming here. And if you give them something to do, they’re coming.”
