There’s a wide swath of Americana between West Coast folk and the hillbilly music of the Eastern United States. And I’m With Her covers all of it on the trio’s full-length debut, See You Around.

Multi-instrumentalists all, Sara Watkins, Sarah Jarosz and Aoife O’Donovan created a mostly acoustic bed of guitars, fiddle, banjo, mandolin, ukulele and keys over which their dreamlike blend soars.

Watkins is a girlish singer with a voice that cracks with melancholy in all the right places; Jarosz is the smooth middle; and O’Donovan possesses a fragile-yet-strong instrument that can coo as well as it roars. And when they come together at strategic points in their songs, those voices create goose-bump harmonies close enough to make one wonder whether the musical partners were separated at birth.

Producer Ethan Johns adds occasional splashes of Dobro and harmonium to the otherwise band-only album, a collection of 11 originals and a cover of Gillian Welch’s unreleased “Hundred Miles.” It follows the group’s 2015 seven-inch and 2017 covers EP, Little Lies.

And it’s those original songs that are See You Around’s strongest calling card. Writing together, Watkins, Jarosz and O’Donovan came up with an LP full of timeless numbers that include a fiddle-driven square-dance instrumental in “Waitsfield,” a heart-wrenching ballad about a game-playing married man in “Close it Down,” a bluesy, reverb-laden pean to romantic love in “Ryland (Under the Apple Tree)” and an old-timey, banjo-heavy travel song that sounds like it could have been written 100 years ago in “Overland.”

The principals have a way with words and their songs are littered with clever turns of phrases such as when Jarosz sings of a wavering lover – “I know you’re looking out for new eyes in the crowd” – on the title track. Elsewhere, O’Donovan protects her mystery – “Everybody wants a piece of me/everybody wants to see what I see/but I can’t just give it to you like that” – on “I-89,” a Joni Mitchell-inspired rocker that’s a cousin to O’Donovan’s solo track “The King of All Birds.”

Simplicity in virtuosity is what makes I’m With Her such a rare commodity. And though it was almost certainly unintentional, the band sums up its musicality on the Watkins showcase “Ain’t That Fine,” a lilting tune that looks at the mundane things in life – memories, friends and loves – that make it so exceptional:

“Some folks have got it better, but, oh, we got it good/we’ve got a story, a dotted line/no need to hurry, take our time/nothing special, ain’t that fine?”

Indeed it is.
