Sleep Theory

Sleep Theory combines energetic hard rock and metalcore with the massive hooks of powerhouse vocalist Cullen Moore. Praised by Jelly Roll and David Draiman, they’ve toured with Shinedown, Falling In Reverse, and Beartooth. In under two years, they became the fifth most-played artist on Active Rock radio. Afterglow and the Paper Hearts EP merge heavy rock with pop and R&B, producing anthemic bangers and emotional ballads. Saluted by Revolver, Loudwire, and Amazon Music as an Artist to Watch in 2025, they’ve become one of heavy music's biggest breakouts.
