‘The Lonely Few’ Review: Rocking Out and Falling in Love

Of all the juke joints in all the towns in all the South, Amy had to walk into Paul’s.

OK, yes, he invited her. A musician with a touch of fame, whom he’s known since she was a child, she’s stopping in for a visit on a break from her solo tour.

For Lila, the front woman of the local band that’s playing the bar that night, the world shifts permanently when Amy glides in, trailing all the glamour and cool of a life so much bolder than anything Lila has ever lived.

“Great set,” Amy tells her afterward. And when Lila bashfully shrugs off the compliment, Amy repeats it. “No, really — great set,” she says, her words unambiguously flirtatious. The chemistry between these two is instant, and profound. As soon as they sing together, so is the harmony.

“The Lonely Few,” the achingly romantic, softly sexy, genuinely rocking new musical by Rachel Bonds (“Jonah”) and Zoe Sarnak at MCC Theater, is Lila and Amy’s love story. The telling of it gives us more of Lila’s world than of Amy’s, though — the same way that the 1999 rom-com “Notting Hill” is grounded more in the world of the ordinary bookseller than of the movie star who wanders in and claims his heart.

Meticulously directed by Trip Cullman and Ellenore Scott, “The Lonely Few” is beautifully cast, and it has an absolute ace in its Lila: Lauren Patten, bringing the full-voiced ferocity that she unleashed in “Jagged Little Pill” — and won a Tony Award for — and the endearing awkwardness that she lent to “The Wolves,” alongside a vulnerability that could just about break you.

In Lila’s tiny Kentucky hometown, music-making is the passion she gets up to when she isn’t working her grocery store job with her bassist and best friend, Dylan (Damon Daunno), or keeping an anxious eye on her brother, Adam (Peter Mark Kendall), whose drinking is out of control.
