With soulful four-part harmonies, poetic lyrics and indelible melodies, it’s easy to see why some hail von Grey as “nothing short of stunning.”

They sound like they were born to play together — and, in fact, they were. The four sisters have been playing music nearly their entire lives.

The group will perform at 8 p.m. Friday, Dec. 7, in the Sautee Nacoochee Center Theatre.

Classically trained from an early age, the Atlanta-based quartet — Kathryn, Annika, Fiona and Petra von Grey — have built on that foundation by performing upward of 200 shows in the past two years, from recurring residency tours at intimate venues throughout the southeastern U.S. to supporting gigs with such artists as Sarah McLachlan.

Their forthcoming five-song EP, recorded with Grammy award-winning producer/engineer Nick DiDia (Bruce Springsteen, Train, The Gaslight Anthem), captures the band’s essence and the raw intensity of their live performances.

“There are times when musical expression is more important than perfect execution,” explains Fiona. She and Annika are von Grey’s lead vocalists and chief songwriters.

“There are times I want to hear my fingers slide on the guitar string, when the breath I take before a phrase is as important as the lyric that follows.”

Working in a vein similar to that of such contemporaries as The Civil Wars and Mumford & Sons, von Grey masterfully melds folk, bluegrass and country influences, imbuing time-honored musical idioms with a distinctly modern sensibility.

From the opening “What Am I,” a stirring plea for unity and understanding, to the bittersweet “Shane,” the collection provides a remarkable introduction to von Grey.

“It’s only the beginning,” says Annika. “Each step makes us eager to reach further. There’s always another emotion or thought aching to be shared in just the right way — the rhythm of living.”

Indeed, it’s their attunement to this rhythm that makes von Grey’s songs at once so personal and so universal.

“The first time I heard their harmonies, I got goose bumps. We are so excited about having these wonderful young ladies in Sautee. They are on the fast track to stardom, and I look forward to the day when I can say, they played here on their way to the top,” said Tommy Deadwyler. “We are also pleased that we received a grant from the Fox Theatre Institute to help fund this show.”
