STEUBENVILLE — The June edition of First Fridays on Fourth Street might be the most impressive in the event’s history.

“It’s going to be what I think will be one of the biggest First Fridays yet — we’re doing a tiki theme, an Hawaiian theme,” said Marc Barnes. “We’re going to be doing a secret tiki cocktail bar, where people are going to be able to scout the downtown to find it.”

That’s just one of the attractions that will be part of the monthly downtown street festival, Barnes explained.

He is president of the Harmonium Project, the nonprofit, volunteer-based organization that looks to cultivate joy, music, art and hope in the community. One of the things that has him the most excited about this Friday’s event is the appearance of the band Williamson Branch.

“They are an international Americana band, and they will be kicking the evening off at 6 p.m.,” Barnes explained.

An award-wining family band, the Nashville, Tenn.-based group has built a national following with a blend of bluegrass, country, gospel and harmonies. According to Bluegrass Today, it is a must-see band.

Earlier in the day, members of the band will lead free workshops at the Sycamore Youth Center. A clogging workshop will be held from 1:15 p.m. to 2 p.m., and a fiddle workshop will be held from 2 p.m. to 2:45 p.m.

There are plenty of other activities planned for Friday evening along the stretch of Fourth Street that runs between Washington and Adams streets, Barnes said.

“We’re going to have miniature golf set up throughout the downtown,” he explained. “It’s going to be nine holes, and if it goes well, for the Fourth of July we are going to ramp it up to 18 holes, if we can get a sponsor.”

Sponsorships and donations are critical to ensuring the success of the series, which is in its ninth season and runs through October, Barnes explained.

“Each First Friday costs us about $6,150,” he said. “We run entirely on donations — there are no paid employees or anything like that. It’s just a volunteer initiative, so each year we have to raise funds.”

Anyone who is interested in donating to the effort or becoming a sponsor can contact Barnes at (740) 512-0162. Donations also can be sent by checks made payable to the Harmonium Project and sent to PO Box 772, Steubenville, 43952.

In addition to the usual lineup of performers scheduled throughout the evening on the festival’s various stages and vendors spread throughout the area, there will lots of activities.

“The idea is for one night to make Steubenville into a beach town,” Barnes said. “There will be bouncy houses and games for kids — water games, volleyball, pickleball and gaga ball — that they will be able to play through the night.”

Many activities will be built around the theme, Barnes said.

“Of course, there will be a best Hawaiian shirt competition,” he said. “So, if you come in your Hawaiian shirt, there will be a photo booth set up. You can get your picture taken, and we will select someone as the tiki king of Steubenville.”

He added that there could also be a few more surprises.

“We’ve asked Brody Stutzman, who makes the nutcrackers for the Steubenville Nutcracker Village, to make us a tiki sculpture for the evening,” Barnes said. “Maybe it will have some permanent presence downtown as well.”

Even though the organizers are still working on the June event, they already are looking ahead to the July 3 edition, which will span two days and include a celebration of the 250th anniversary of the United States. Barnes said they still are finalizing details but added Francesca Carinci will be running the Fourth of July parade.

That’s a month away, and for now Barnes says he and the other organizers are looking forward to this Friday.

“It’s going to be a lot of fun,” he said. “It will be different, too. We’re stretching ourselves with this theme. It’s something we haven’t done before.”
