PORTLAND — The acoustic country duo Day for Night will bring its classic harmonies and unmatched original material to the Portland wine bar Blue at 6 p.m. Friday, Jan. 10, at  650 Congress St.

Hailing from northwest Portland, where the lonesome winds howl, the big rigs growl and the Presumpscot River prowls through the hills, Doug Hubley and Gretchen Schaefer support their singing with guitar and mandolin. Their inspirations include Webb Pierce, Lefty Frizzell, George Jones, Gram Parsons and Emmylou Harris, and some of country’s premiere brother acts — the Stanley Brothers, the Everly Brothers, the Louvin Brothers.

The pair, who first made music together in the 1990s as members of the Cowlix and the Boarders, combine wry humor with a bedrock reverence for musical tradition as they cover about four decades’ worth of country music in addition to a growing list of Hubley originals.

“I like being part of the history of country music,” said Schaefer, whose first exposure to the style was hearing her father play Hank Williams songs on a Gibson archtop. “It’s a long history that, really, goes back centuries, back to England. Whether the songs we’re doing are older or newer, it’s satisfying to be part of that lineage.”

“I guess we’re part of the Americana scene, but we occupy a middle ground that’s not heavily populated these days,” said Hubley. “We nod, sort of, to a lot of country traditions — like Appalachian music via the Stanley Brothers, or honky tonk via Webb Pierce and Buck Owens. But we’re products of the New England suburbs, and we approach those sounds and themes from that perspective. It’s cathartic, but there’s still that New England reserve and irony.”

Day for Night is a popular attraction at the annual Cornish Apple Festival, where Hubley and Schaefer have performed since 2008. The band has also appeared at the Royal Bean, in Yarmouth; the Cornish Inn; the Frog and Turtle Gastropub, Westbrook; the Last Church on the Left, Portland; and in Bates College appearances including the BatesDowntown series.

Previous incarnations of the band, including the Boarders, the Cowlix and the Fashion Jungle, played at the Maine Festival, Geno’s, the Maine College of Art, on WMPG-FM and at numerous other nightclubs and private functions.
