David Dunn: President of G.H. Dunn Insurance and…rock star?

Dunn, a Mattapoisett resident, spends his week dealing with insurance and his weekends playing bass guitar and singing in Huxster, a three-piece power-pop band.

With the help of Watertown guitarist Paul Amenta and Carver-based drummer Joe Patten, Dunn released Huxster’s second album, “Side Two,” Nov. 12. The band is playing a special acoustic show at the Gateway Tavern in Wareham on Friday, Nov. 18.

Huxster’s first album, “Snake Oil,” came out in 2009, a result of Dunn laying down some tracks he’d had for awhile. Armenta and Patten were recruited to play as well, and after the recording was over, they all said, “Let’s make a band out of this.”

“It’s funny,” Dunn says, “because we made an album first, then became a band.”

“Side Two,” however, is a totally new approach.

“These are songs we’ve been playing live for awhile now,” Dunn says. “We’ve spent the last year playing shows and seeing what works and what doesn’t, how the crowd responds, that sort of thing. We’ve all collaborated on the songwriting this time around.”

The band did some recording at The Outpost in Stoughton with legendary producer Jim Siegel, whose credits have showed up on albums from The Mighty Mighty Bosstones and the Dropkick Murphys.

But “Side Two” also has a taste of Mattapoisett in it.

One of the album’s singles, “Island,” features an organ track recorded at the Mattapoisett Museum.

“We used a 100-year-old pump organ that’s at the museum,” Dunn says. “[Curator] Bette Roberts was all about it. She loved it.”

Additional recordings were done in a small upstairs room at the former G.H. Dunn Insurance building at 55 County Road, which also serves as the band’s practice space.

The new album is currently getting airplay at four local stations and has been sent to over 400 stations across the U.S. and Canada.

A handful of big shows are in the works to celebrate the album, including a New York City release show at Arlene’s Grocery.

Dunn is also writing music for an upcoming independent movie by Ernest Thompson, screenwriter for the Henry Fonda and Katharine Hepburn film, “On Golden Pond.”

And how does this rock star lifestyle mingle with Dunn’s insurance job?

“I think people are more inclined to do business with me,” Dunn says. “They can see I’m not just all about insurance!”
