Info for Afterglow

With their debut album, Afterglow, Sleep Theory is carving out space at the forefront of modern hard rock, stacking stadium-sized hooks with genuine emotional weight. If their meteoric rise is any indication, this is only the beginning. The album, which offers a stunning display of diverse rock flavors, was produced by David Cowell and mixed by Zakk Cervini (Bring Me The Horizon, Bad Omens, Architects).

Revolver put it best: “The band’s mix of metalcore, pop, and R&B is clearly connecting in a big way—and has positioned Sleep Theory as one of heavy music’s biggest breakouts.”

Sleep Theory isn’t just another rock band climbing the ranks—they’re an unstoppable force rewriting the genre’s rules in real time. Frontman Cullen Moore doesn’t just sing; he commands, delivering lung-busting hooks that sit comfortably between modern rock’s heaviest hitters and the emotional pull of early-2000s alt-metal. Sleep Theory’s sound blends anthemic rock, metalcore energy, and smooth R&B-inspired melodies, drawing comparisons to Linkin Park’s more dynamic moments. Moore’s vocal range allows for a mix of soaring melodies and intense screams, adding depth and versatility to their music.

In under two years, the Memphis-based quartet—Moore, bassist Paolo Vergara, guitarist Daniel Pruitt, and drummer Benjamin Pruitt—had rocketed from internet obscurity to festival mainstages and the momentum hasn’t slowed. With over 220 million streams on their first eight songs, Sleep Theory is proving that viral moments can have serious staying power.

The industry is watching. Sleep Theory closed out 2024 as the fifth most-played artist on Active Rock radio, with multiple singles cracking year-end rock and metal charts. Heavyweights like Jelly Roll and Disturbed’s David Draiman are openly singing their praises, while Shinedown, Beartooth, Wage War, Daughtry, and Falling in Reverse have already taken them on tour across the U.S. and Europe.

The goal is to write songs that, if you were to strip everything away, would still work as full-on, classic pop tracks that are super memorable yet deeply resonate with people […].” (Cullen Moore)

"Assured, significant, powerful. Afterglow is a shimmering collection of tracks that has seen a band release on their own regard, ensuring their songs become a representation of their own story, and not the timeline dictated by the changes and tribulations that arise from moments beyond our control. With this, Sleep Theory have put forward 12 tracks dripping in authenticity, whilst also fostering a sound style that is so inextricably connected to the current culture of pop, metalcore, and everything in between- making it a universal delight of colourful musicianship. Track after track, the band pushes the envelope, not just to the parameters of the genre they were once defined by, but of the music we thought possible; they have truly become pioneers of creative expansion and expression, all backed by their own liberty and choices. In a time where metalcore can be so much more, Sleep Theory have taken the wheel, driving through the stoney walls to new and wondrous plains." (Georgia Haskins, wallofsoundau.com)

Sleep Theory
delivers the dynamic, heavy bounce and massive vocal hooks that the rock world desperately needs. Cullen Moore is a powerhouse singer who outmatches nearly all his peers, recalling the most classic and timeless pop, R&B, and rock n’ roll vocalists of the last several decades.

In less than two years, they became the fifth most-played artist on Active Rock radio, with three songs on the year-end rock charts on YouTube and Amazon. “Fallout” was the ninth most-played song on Active Rock in 2024. Jelly Roll and David Draiman sing the band’s praises. Shinedown, Falling In Reverse, Beartooth, Nothing More, Wage War, Set It Off, and Daughtry have taken them on tour.

On Afterglow, Sleep Theory’s full-length debut, and the Paper Hearts EP, the band’s rich, emotional sound combines anthemic heavy rock like Linkin Park and Bring Me The Horizon with pop and R&B, equally adept at breakdowns and ballads. Amazon Music, Loudwire, and Revolver named them an Artist To Watch in 2025. Revolver rightly declared, “The band’s exciting mix of metalcore, pop, and R&B … has positioned Sleep Theory as one of heavy music’s biggest breakouts.”

Sleep Theory pushes themselves creatively at every turn, catapulting the genre to new sonic heights.
