Amy Shark, “Sunday Sadness.”

Australian singer-songwriter Amy Shark built her musical foundation on hyper-personal songs, traversing her own internal monologue and tendency to overthink. Those deepest, most intimate lyrical moments brought a universal relatability of shared experiences, anxieties and desires. On her third album, Sunday Sadness, she dives back into the deep end, but this time with some unexpected decisions to convey emotion.

One of the best examples of this is the punky and anthemic “Two Friends.” Shark is a self-described blink-182 super fan, and she does a great job of bringing the pop-punk attitude with her emotive style. The name-drop game of telephone in the bridge is an especially fun twist and is surprisingly infectious.

The upbeat and rhythmic “It’s Nice to Feel This Way Again” takes things in a different direction with its snaps and handclaps providing the backbeat. The song is atmospheric and spacious; Shark’s voice warm and lush, amply filling the page.

“I want to feel you in my world again,” Shark sings.

The bouncy pop rock continues on the anxious longing of “Can I Shower At Yours,” a lively ode about the laws of attraction with wordy verses that help convey the optimistic butterflies. Sunday Sadness excels at not dwelling on one emotion or sound too long, providing a full palette from which to draw. At the same time, the lyrics stray away from some of the more angsty and self-deprecating moments of Shark’s prior records. Still, she continues the conversation with herself, writing her thoughts down on paper as she does on acoustic ballad “Beautiful Eyes.”

“I remember when I was 17/ ‘Amy, why you always gotta disagree?’/ My mother was a baby with a baby like me/ My boyfriend at the time wasn’t nice to me,” she sings.

At just two minutes, opening track “Slide Down the Wall” is quick hitter, but manages to cover a lot of territory in that time, building into an alt-pop tune. The upbeat “Gone” has a similar alt sound while mixing in a dash of pop-punk snark.

As a complete work, Sunday Sadness may be Shark’s most cohesive record from front to back, with a balanced mix of the familiar and unfamiliar all fitting under the same umbrella.

“Loving Me Lover” is a traditional pop tune, but the production and dialed-in harmonies, with a mix of sung and spoken-word delivery, elevate it to a more memorable song.

There also more earnest and intimate tracks like “Babe” and “I’m Sorry,” which deliver quieter moments that give a nod to Shark’s earliest work as a folkier artist.

Hands down, the album’s best moment is the one that likely holds the most meaning to Amy Shark. She and blink-182 vocalist Tom DeLonge trade vocals back and forth on “My Only Friend,” a stinging ballad about a party gone awry.

“If he tries that shit again, say you’re here with me,” she sings. The two voices meld perfectly, and the track brings everything that Shark excels at, from the lyrics to the delivery and the vibe. And if you’re keeping count, she’s now worked with all three members of her favorite band.

The album closes out with quiet acoustic cut “Our Time Together.” Amy Shark may have grown to be a superstar in Australia, but records like Sunday Sadness are proof she’s deserving of a similar explosion here.
