MiniBio

He’s a singer and musician best known as the lead vocalist of the band Sleep Theory, a rising name in the rock scene. Fans recognize him for powerful tracks like “Another Way” and “Numb,” both standout songs from the band’s debut album, Afterglow. Before all the spotlight, he was just a music-loving kid growing up just south of the Tennessee-Mississippi border—a place he affectionately calls Memphissippi. Music clearly runs in his blood; his father, grandmother, uncles, and aunts were all singers, so it’s no surprise that he found his way to the mic.

But before fully diving into his music career, he served proudly in the U.S. Army. It wasn’t until after his military service that he seriously began pursuing music as a full-time passion. In 2019, he founded Sleep Theory, initially as a solo project. However, it didn’t take long for the sound to grow—soon, the project evolved into a full band with a bassist, guitarist, and drummer joining the lineup.

Together, they released their debut EP, Paper Hearts, in 2023, marking a major milestone in his journey. From Memphissippi to the stage, his path has been shaped by discipline, heritage, and an undeniable love for music. And as Sleep Theory continues to gain momentum, he remains at the heart of it all—driving the vision, voice, and energy that define the band’s evolving sound.

Trivia

Sleep Theory’s debut single, “Another Way,” really took off in 2023, quickly gaining momentum on TikTok. Within just 36 hours of its release, the track racked up over half a million views—an impressive milestone that put Sleep Theory on the map. And honestly, it’s not too surprising when you consider his background. Sleep Theory often talks about how his time in the military shaped him, instilling a strong work ethic and discipline that he now brings to every aspect of his music career. Sleep Theory’s dedication, combined with that early viral success, shows just how much potential Sleep Theory has moving forward.
