CORNISH — The acoustic country duo Day for Night will bring its classic harmonies and unmatched original material to the Cornish Apple Festival at 9:30 a.m. Saturday, Sept. 27, and to the Portland wine bar Blue at 6 p.m. Friday, Oct. 10.

Day for Night has performed every year since 2008 at the popular apple festival, held in Cornish’s Thompson Park, on Route 25. The duo is a regular presence at Blue, located at 650A Congress St. Learn more at www.cornish-maine.org/about_cornish_apple_festival.html and http://portcityblue.com/.

Hailing from northwest Portland, where the winter winds howl, the big trucks growl and the Presumpscot River prowls, Doug Hubley and Gretchen Schaefer support their singing with guitar and mandolin. Their inspirations include Merle Haggard, Webb Pierce, George Jones, Gene Clark, Gram Parsons and Emmylou Harris, as well as some of music’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 tradition as they cover about four decades’ worth of country music — in addition to a growing list of Hubley originals such as “You Wore It Well,” “Where Was I,” “I Never Drink Alone,” “Bittersweet” and “The Ceiling.”

“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. 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.”
