After a four-year hiatus, live music has returned to Harlow’s Pub.

Co-owner Brian Zimmer said bringing live music back has always been part of the plan, and the public demand has been high.

“We’ve heard a from a lot people asking when we would start the music up again, so we’ve been working hard getting it going,” Zimmer said. “People talked a lot about how the music had stopped. It was obvious we should try to revive it. It’s a key element of the identity of Harlow’s — one of the first things that comes to mind when people think about Harlow’s.”

Zimmer said getting the shows organized has definitely been a learning curve.

“Organizing and booking shows and executing shows is a ton of work. I have a lot admiration for the people who organized this in the past. It is pretty interesting to learn about. It’s all juggling lot of different moving parts,” Zimmer said.

Zimmer said he has been surprised by the depth of live music and performers in the region.

“We’ll never run out of bands. There is no shortage of really good bands that would like to play here. It’s really hard to fit them all in; we actually have more options than we have time,” Zimmer said. “There is just so much music in this region. Its incredible; it has to be unusual.”

The first event Zimmer and co-owner Tim Selby brought back was the the pub’s live bluegrass jam. The jam, which takes place every Thursday night from 8 to 10 p.m., is hosted by local bluegrass musician John Meehan.

“The jam has happened about 10 times since relaunching in October, and we’ve consistently had eight to 10 people show up and play,” Zimmer said. “Any bluegrass musician is welcome to come and play.”

The pub is also relaunching ticketed live music shows, which typically start around 8:30 or 9 p.m., after the dinner hour has wound down. Shows are 21 and over.

The relaunch of live music at Harlow’s has inspired some bands back together for the occasion. On Dec. 14, Youngest Sun, which was started in Peterborough by Duncan Pelletier, returned to the Harlow’s stage.

“They all live on the Seacoast now, and they hadn’t played together for a while, but Duncan organized it. They all got back together just for that show. A lot of people used to turn out to see them play live, so people were super excited about it,” Zimmer said. “They have a real following.”

On Dec. 21, the Harlow’s stage hosted Hovercraft, featuring Seth MacLean, who is well-known around town as Peterborough’s assistant town administrator.

MacLean, who plays in several bands, was one the first local acts to return to the Harlow’s stage.”

“I am thrilled to see live music making a comeback at Harlow’s, thanks to the new ownership recognizing this incredible venue as a central gathering spot in the Monadnock region. I’m honored to be a part of their programming. I’ve had the pleasure of performing with several small projects in the area at Harlow’s, and it was truly special to be the first band to play there in years,” MacLean said.

MacLean, who plays in several bands and travels around New England to perform, feels Harlow’s is unique.

“For me, Harlow’s is the best small venue in New England, and we’re incredibly fortunate to have this gem right in our own backyard. As a part-time musician who has performed at venues throughout the Northeast, Harlow’s is by far my favorite place to both perform and experience live music,” MacLean said. “Even before I settled in Peterborough, I had the pleasure of playing there multiple times over the years, always drawn to the venue’s vibrant energy and strong community support. Harlow’s is truly a special space, built up by Dave Szehi, his remarkable staff, the unwavering support of the Peterborough community, and countless musicians who chose to venture off the beaten path to perform here. Now, a new ownership group and staff, who share that same passion, are continuing the legacy and putting in the hard work to ensure this small venue thrives.”

Zimmer said he and Selby are looking to host a range of music on the stage.

“We’re trying to mix it up with different types of music, to have something that appeals to everyone, not always the same type of music. Not just cover bands, or not just one style. We are looking to have something for everyone.”
