Nick Offerman and Kiersey Clemons in Hearts Beat Loud.

Nick Offerman and Kiersey Clemons are a winning, inspiring father-daughter team in Hearts Beat Loud, a musically infused cinematic gem that will stand as one of this summer’s under-the-radar greats.

Frank (Offerman), a record-store owner (he sells mostly vinyl) with a gruff attitude, is dealing with tough economic times—which is not good, considering his daughter, Sam (Clemons), is about to leave for medical school. He informs his landlord, Leslie (Toni Collette, having a great year), that the store will be closing. Frank finds himself at a sort of spiritual crossroads.

He takes solace in his mandatory musical jam sessions with his kid. Both of them are decent-enough musicians; in fact, Sam is actually pretty damn good. She has a knack for songwriting but doubts her talents. Frank pushes her to create, marvels in what she’s able to come up with, and suggests they form a real band.

Sam pushes back, wanting to focus on the whole becoming-a-doctor thing, but Frank persists, ultimately uploading one of their demos to Spotify. He hears the song in a coffee shop one morning—and it’s a great moment. As a testament to how the face of the music industry has changed, an artist hears his music streaming on somebody’s “mix” rather than on the radio in his car. The film is somewhat of an endorsement for Spotify and vinyl.

None of this would work if the music stunk. It doesn’t—it’s good. Offerman and Clemons combine for some sweet music-making, including the film’s title track, one that is repeated often in the movie. Offerman is no Hendrix, but he handles his guitar parts with enough finesse to make you think he’s been playing for a long time, while Clemons is a natural wonder with a great voice.

It must also be said that the people in this movie have great musical taste. The soundtrack and the characters reference a who’s-who of great artists, including Ween, Animal Collective, Jeff Tweedy, Spoon and Mitski. Hearts Beat Loud is the best music-store movie since High Fidelity.

Even more inspiring than the music is a love story between Sam and new-friend Rose (American Honey’s Sasha Lane). Their relationship’s depiction surprises in that it’s allowed to happen without any discussion—it’s just two people falling in love. The film’s other love story—the bond between father and daughter and their musical adventure—is equally lovely.

Offerman, a successful comedic actor, is proving he’s also a dramatic real deal. He had a good co-starring role as a stoner in The Hero, last year’s ode to actor Sam Elliott. He also killed it as one of the McDonald brothers in The Founder. This time out, he has a starring role that allows him to show all kinds of range. The final look he gives his daughter in this movie is priceless.

As the movie’s true heart, Clemons boasts a beautiful singing voice to go with her solid acting chops. She and Offerman are strong enough here to overcome the few moments when director and co-writer Brett Haley (who also directed Offerman in The Hero) drifts into obvious territory. The material is never bad, but there are moments that could’ve been hokey if it weren’t for Clemons and Offerman making them better.

Collette, who deserves awards consideration for her barn-burning work in Hereditary, lends a lot to the film in her supporting role, including a karaoke moment that reminds us that she can sing. Also: Let it be said that it’s always great when a production can coax Ted Danson into playing a bartender.

So, yep, Hearts Beat Loud has real music, real love, and Sam Malone slinging drinks—and as a result, it’s a resounding success. If Offerman and Clemons don’t win you over here, you are a super-grouch.

Hearts Beat Loud is now playing at the Palm Desert 10 Cinemas (72840 Highway 111, Palm Desert; 760-340-0033).
