Blue Heart's Revelry has been performing throughout the Lehigh Valley since the band's initial formation in 2012.
It took six years and a handful of lineup changes for the Easton-based bluegrass-folk group to find their musical comfort zone -- the result of which has led to an ever-evolving sound.
"The basic incarnation was a three-piece. We were way more bluegrass than we are today," vocalist-banjoist Lucas Sutphen said during a March 21 phone interview. "With all of the different members coming and going, we definitely got a little louder and a little more rock 'n' roll; a little more high-powered, if you will."
Blue Heart's Revelry will open Saturday's "Stage on Stage" concert at the State Theatre in Easton. The show will also feature performances by New Jersey-based folk-pop trio The Happy Fits and Nashville's Forlorn Strangers.
During "Stage on Stage," fans and bands will share the theater's historic main stage, which will be transformed into a club-style atmosphere. (The first "Stage on Stage" concert, held in January, featured Americana-rock outfit Acoustic Kitty Project and blues rockers The Trongone Band.)

"It's an opportunity not really given to local bands. It's such a rare occasion," Sutphen said of the concert. "I'm really looking forward to being on the stage... It's the oldest, most historic (venue) in Easton and to be given the opportunity to be there and share the stage with other fantastic acts and show our hard work is really special."
Blue Heart's Revelry released the album Until You're Gone in 2017. Sutphen said the band had begun writing music for the album but put it on hold with the addition of vocalist-guitarist Joe Burley and violinist Dan Stevens in early 2016. He said the group is hoping to release a five-song EP this summer.
"We got a lot of songs that haven't been recorded yet. We have a lot of catching up to do," he said. "it's been kind of a wild ride."
Sutphen said the appeal of bluegrass and folk music lies in its rawness and simplicity. "It's bare bones and anybody can relate to it. I believe that without heart and soul, there's no reason to write a song."
Blue Heart's Revelry will perform Saturday, along with The Happy Fits and Forlorn Strangers, during "Stage on Stage" at the State Theatre in Easton. Show time is 7:30 p.m. Tickets cost $12.50 in advance, $15 at the door.
