The Church Sisters prove they're a duo to keep your eye on with their debut single "7 Years," a Lukas Graham cover. The new song features spot-on harmonies from the real-life sisters.

The Church Sisters are fraternal twins Savannah and Sarah Church, and they were recently signed to Valory Music Co., which is an imprint of Big Machine Label Group. While Savannah takes the lead on the song, Sarah accompanies her pristine vocals flawlessly. Together they sing about the ups and downs of childhood before the adventures that come with being 20, and then 30 years old.

The stripped-down track puts a country spin on the pop hit with wavering pedal steel and Sarah's poignant harmonies. A memorable cover, it is evident that the sisters have been perfecting their blended voices since they were children.

Did You Know?: The Virginia natives began singing in public when they were 12 years old, and previously had a family band. They are currently working with producer Julian Raymond (Glen Campbell, Hank Williams, Justin Moore).

The Church Sisters, "7 Years" Lyrics:

"Once I was seven years old my momma told me / Go make yourself some friends or you'll be lonely / Once I was seven years old / It was a big big world, but we thought we were bigger
 / Pushing each other to the limits, we were learning quicker / By eleven smoking herb and drinking burning liquor / Never rich so we were out to make that steady figure."

"Once I was eleven years old my daddy told me / Go get yourself a wife or you'll be lonely / Once I was eleven years old."

"I always had that dream like my daddy before me / So I started writing songs, I started writing stories / Something about that glory just always seemed to bore me / 'Cause only those I really love will ever really know me."

"Once I was 20 years old, my story got told / Before the morning sun, when life was lonely / Once I was 20 years old."

"I only see my goals, I don't believe in failure / 'Cause I know the smallest voices, they can make it major / I got my girls with me at least those in favor / And if we don't meet before I leave, I hope I'll see you later."

"Once I was 20 years old, my story got told / I was writing about everything, I saw before me / Once I was 20 years old."

"Soon we'll be 30 years old, our songs have been sold / We've traveled around the world and we're still roaming / Soon we'll be 30 years old."

"I'm still learning about life / My woman brought children for me / So I can sing them all my songs / And I can tell them stories / Most of my girls are with me / Some are still out seeking glory / And some I had to leave behind / My brother I'm still sorry."

"Soon I'll be 60 years old, my daddy got 61 / Remember life and then your life becomes a better one / I made a man so happy when I wrote a letter once / I hope my children come and visit, once or twice a month."

"Soon I'll be 60 years old, will I think the world is cold / Or will I have a lot of children who can warm me / Soon I'll be 60 years old / Soon I'll be 60 years old, will I think the world is cold / Or will I have a lot of children who can hold me / Soon I'll be 60 years old."
