Who is Sleep Theory?

In less than two years, Sleep Theory has skyrocketed from a “new name” to the 5th most-played artist on Active Rock radio. They are widely considered one of heavy music’s biggest breakout acts.

• The Sound: A high-energy blend of Hard Rock, Metalcore, and smooth R&B. Think Linkin Park meets Bring Me The Horizon with massive pop hooks.

• The Voice: Lead singer Cullen Moore is being hailed as a “powerhouse” whose range rivals the most iconic pop and R&B vocalists of the last 30 years.

• The Resume: They have already toured with giants like Shinedown, Falling In Reverse, and Beartooth.

• The Hype: Named an “Artist to Watch in 2025” by Amazon Music, Loudwire, and Revolver.

Why You Can’t Miss This Show

Sleep Theory is known for their “dynamic, heavy bounce.” Whether you’re looking for aggressive breakdowns or emotional, anthemic ballads, their debut album Afterglow and the Paper Hearts EP deliver both.

Even industry legends like Jelly Roll and David Draiman (Disturbed) are publicly singing their praises.
