Folk act Darlingside plays Volcanic Theatre Pub on Friday.

The Massachusetts roots-pop band Darlingside has played Central Oregon a handful of times, including at least twice at the Sisters Folk Festival. I caught them in 2014, when I thought they were one of the highlights of the lineup and described them thusly:

“Darlingside is four young dudes whose harmony-heavy songs crackle with energy. They started off doing ‘Open Door,’ an incredible, almost a cappella song with the kind of melody that’ll stop you dead in your tracks.”

They followed that with a cover of the Smashing Pumpkins’ “1979,” which cinched my positive opinion of them.

Not much has changed in the years since: Darlingside’s music still revolves around their incredible voices, which sound like one of those Il Divo-style vocal groups mounted onto baroque arrangements by a progressive folk band. Their latest album, “Fish Pond Fish,” according to the group’s website, “catalogues the weird nooks of our world with the same curiosity of a botanist’s time-worn field journal.”

Darlingside, with Andrea Von Kampen: $25, 8 p.m. Friday, Volcanic Theatre Pub, 70 SW Century Drive, Bend, volcanictheatre.com.
