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 summerโ€™s under-the-radar greats.

Frank (Offerman), a record-store owner (he sells mostly vinyl) with a gruff attitude, is dealing with tough economic timesโ€”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 sheโ€™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 morningโ€”and itโ€™s a great moment. As a testament to how the face of the music industry has changed, an artist hears his music streaming on somebodyโ€™s โ€œmixโ€ 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 doesnโ€™tโ€”itโ€™s good. Offerman and Clemons combine for some sweet music-making, including the filmโ€™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 heโ€™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 whoโ€™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 Honeyโ€™s Sasha Lane). Their relationshipโ€™s depiction surprises in that itโ€™s allowed to happen without any discussionโ€”itโ€™s just two people falling in love. The filmโ€™s other love storyโ€”the bond between father and daughter and their musical adventureโ€”is equally lovely.

Offerman, a successful comedic actor, is proving heโ€™s also a dramatic real deal. He had a good co-starring role as a stoner in The Hero, last yearโ€™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 movieโ€™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 couldโ€™ve been hokey if it werenโ€™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 itโ€™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 drinksโ€”and as a result, itโ€™s a resounding success. If Offerman and Clemons donโ€™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).
