NEW HAVEN — The Brother Brothers — as in identical twins Adam and David Moss — will bring their acoustic music and sibling harmonies to the First Presbyterian Church Hall Jan. 5 in the first CT Folk “Folk Fridays” show of 2018.

Showtime is 7:30 p.m. Admission is $20 for adults and $10 for children and students, with adult admission available for $15 in advance at ctfolk.com until 3 p.m. on Jan. 5. First Presbyterian Church is located at 704 Whitney Ave. in New Haven.

The Brother Brothers, originally from Peoria, Illinois, but now based in Brooklyn, New York, are an acoustic duo that features David Moss on cello and guitar and Adam on five-string fiddle. Their music blends the influences of Appalachian, klezmer and bluegrass music traditions, among others.

Since joining together as a duo in 2016, the two — each of whom had already established themselves individually in the Americana music world — have carved out their own niche, sharing stages along the way with the likes of Sarah Jarosz, Lake Street Dive, Eileen Ivers and The Felice Brothers.

The Brother Brothers recently have taped sessions for Daytrotter, Audiotree and Music City Roots and have performed at The Kennedy Center, NERFA (Northeast Regional Folk Alliance) and Folk Alliance International.

They released an EP, “Tugboats,” in January and are planning to release a follow-up full-length album in early 2018.

“The Brother Brothers have been in this together for life, and their familial connection comes through in the music, harkening back to some of the greatest family harmonies ever made,” said Jarosz in a quote in the brothers’ online bio.

“They approach their poignant and often-charming songs with an almost startling sense of ease, and the tight harmonies are enough to send shivers down anyone’s spine,” she said. “Their ability to pull the listener into their quietly energetic musical journey is a joy to behold. I can’t wait to be out on the road with Adam and David and hear their heart-wrenching songs and spot-on harmonies night after night.”

In addition to their work together, Adam Moss also tours with Boston’s Session Americana, Brooklyn’s The Defibulators and Ana Egge, and formerly toured with Anais Mitchell’s “Hadestown” and Texas’ 3 Redneck Tenors.

David Moss moved to Austin, Texas, in 2007, where he played with trio The Blue Hit, attended the Kerrville Folk Festival and began playing guitar and writing songs. By summer 2011 he was a finalist in the prestigious New Folk competition, which he ultimately won.

He still performs with The Blue Hit as well as groups such as the Satellite Ballet, Moishe Circus, The Broken Stares, Ana Egge, Roy Williams and The Human Hands and others.
