In 2018, Dayglow (aka Sloan Struble) completed his debut album Fuzzybrain during his senior year of high school in Fort Worth, Texas. Recorded with minimal resources, it remained in relative obscurity for a short while—a sublime slice of bright-eyed bedroom pop that begged to be discovered. Shortly after, the singer-songwriter went on to study advertising at the University of Texas with no interest in pursuing mainstream stardom. That is, until the music video for “Can I Call You Tonight?” became a runaway crossover hit—which Struble shot on a shoestring budget using green-screen effects and has since netted hundreds of millions of YouTube streams. Naturally, it was a lot for Struble to take in. Reflecting on his rise, Harmony House has him dealing with the crazy changes that happened so quickly in his life. “'Cause if you wanna keep on growing, you’ve gotta leave some things behind,” he muses on the mellow “Woah Man,” reassuring himself that letting go is okay as he calmly strums his guitar. But Struble approaches his music with a glass-half-full optimism, and as such, the album’s billowing indie pop has an airy, carefree vibe that could make even the toughest cynic smile. Whether he’s whistling his way through slick yacht rock (“Medicine”) or pivoting into Wild Nothing-recalling dream pop (“Balcony”), Struble makes even the most lovesick sentiments go down easy. But it’s his taste for ’80s soft-rock that resonates the most throughout, like on “December,” on which he contemplates wanting a fresh start along with a smooth sax solo that would make legendary session musician Phil Kenzie proud.
