"Songbird" is a word bandied about a lot to describe vocalists, but in the case of Jess Wolfe and Holly Laessig, it's too apt to avoid.
Like a pair of swallows flying in tight formation, Wolfe's and Laessig's vocals twine about each other in harmonies so knife-sharp and precise they're shocking even to their bandmates in the Brooklyn-based pop quintet Lucius.
"When they're singing, I'll try and figure out who's singing what part, and all of a sudden, they'll sing the same thing," says guitarist/vocalist Peter Lalish. "They just went into this [band] as, 'Hey, let's do this as one two-headed beast with one sound, one voice.'"
Despite their almost biologically identical vocals and playfully identical costumes and silver-dyed hair, Laessig and Wolfe are not related. They first met as vocal students at Berklee College of Music in Boston, where they participated in a number of projects together before meeting fellow Berklee alums Lalish and Danny Molad (drums/vocals).
Molad and Lalish had been collaborating for more than a decade when they met their future co-lead vocalists, who chose Molad's studio to produce a four-song EP. After hearing their preliminary recording for "Go Home," Lalish says, he became enthralled with their vocal chemistry.
And when Molad invited him to lend his talents to the project, he jumped at the opportunity, quickly discovering that the girls were as easy to work with as they were to listen to.

"It was a pretty quick thing when we all started playing together and realizing the potential of collaborating with one another," Lalish recalls. "We all had these eye-opening moments of, 'Whoa, this is a really fast way to arrange a song.'
"It's a lot of ideas going on, but we manage to come to conclusions quickly, and I think we all realized the potential for how well we could work together. It was a pretty immediate thing."
After five years together -- the last two with the addition of multi-instrumentalist Andrew Burri -- Lucius has been on a decidedly vertical ascent recently. In 2013, the band's country/folk/pop-inspired, harmony-centric music attracted notice from prominent outlets such as NPR, Rolling Stone, Billboard Magazine and The New York Times.
Friday night, July 18, the band will make its Chattanooga debut as the headliner of this week's Nightfall concert.
The rush of accolades has been wonderful, Lalish says, but their attention lately has been thoroughly consumed by the rigors of what has essentially been two straight years of nonstop touring.
Not that he doesn't take a moment every once in a while to be properly in awe, he says.
"You try to reflect as much as you can and soak it in, like, 'I want to remember this moment. This is an amazing show,' but everyone is running their engines pretty hot, so there's not a lot of time to do that," he says. "It's always a surprise when I hear those things, and it's really cool."
