Dailey & Vincent

It's one of the most distinctive sounds in bluegrass music – Darrin Vincent's laugh. His partner in Dailey & Vincent – Jamie Dailey talked about that infectious and unique sound.

"He gets tickled all over himself sometimes, and we have to take him back to the bus and lock him up until he gets over it," he joked in an exclusive interview with Billboard. "We've talked about trademarking it, and Rounder has even talked about putting a ring tone out with his laugh. When it goes off, you will not miss your phone call!"

The highly respected duo will release "Brothers Of The Highway" on Tuesday, which is their first pure bluegrass release since 2009's "Brothers From Different Mothers."

"It's been a while since we have had a traditional bluegrass release," he said. "It was a lot of fun to do. We picked a lot of our favorite songs – some new and some old. We wrote a few, and had a lot of fun doing it."

The duo has been far from silent in that time, however. They have enjoyed success with 2010's "Dailey & Vincent Sing The Statler Brothers," as well as 2012's "The Gospel Side of Dailey & Vincent" – both exclusives to the Cracker Barrel Old Country Store chain. Dailey said those albums were very well received – in and out of their fan circle.

"The Statlers record really brought us a lot of new fans – a lot of their fans started showing up at our shows. That was really cool to see. The Gospel Side Of Dailey & Vincent stressed all the sides of Gospel music, and we started getting a lot of Gospel fans at our shows as well. Both of those records were really fun for us to cut, but we felt like it was time to get back and do another hardcore bluegrass record with some original material."

The title cut of the disc was originally recorded by George Strait in 2008, and Dailey said they wanted to bring it into the bluegrass realm – but keep the original sound of the track. "We tried to keep it as authentic as we could, yet not lose the feel of the song. Sometimes, that's hard to do. We really tried to accomplish that."

Another highlight is a cover of the classic "When I Stop Dreaming." What led them to tip their hat to the 1955 Louvin Brothers classic? Dailey smiles and says "We don't know any better. We love the Louvin Brothers, and nobody sang tenor better than Ira. He was a hoss. We couldn't wait to cut it. If anyone out there is unfamiliar with the Louvin Brothers, they owe it to themselves to go back and listen to their recordings. Just heartfelt singing all the way around."

One of the most personal cuts for Dailey is "Back To Jackson County," which he says came from personal experience. "I wrote that one about my hometown – where I grew up. It consists of things that we did when I grew up – fishing, horseback riding, picnics, the church bells on Sunday mornings. Growing up where I did, God, church, family, home and music is really important. I tried to incorporate all of things and tell the story about where I come from."

All told, Dailey is glad that the duo is back out with a traditional bluegrass release – though that's not to say he doesn't like some of the musical detours they have taken. The bottom line is – they just love to sing – and if you've ever seen them live, it shows.

"I don't know if we do that good or not [singing other genres], but whatever we sing, we're singing it because we want to, and because we're enjoying what we are doing with it."
