Fresh off a captivating performance at Louisville's Louder Than Life Festival this past weekend, breakout four-piece Sleep Theory — vocalist Cullen Moore, guitarist Daniel Pruitt, bassist Paolo Vergara, and drummer Ben Pruitt — have released their Paper Hearts EP today, September 29, via Epitaph Records. Get it here

The EP features two buzzy singles — "Numb" and "Gone or Staying" — which have established Sleep Theory as one of the most exciting and talked about bands of 2023. 

"As Sleep Theory, we've poured our hearts and souls into crafting our debut EP Paper Hearts and we're beyond thrilled to share this musical journey with the world," the band shares. "Each track is a piece of our collective soul, woven into melodies and lyrics that resonate with our experiences and emotions. Paper Hearts is not just music; it's our story, our passion, and our dreams set to sound." 


"Another Way" 
"Gone or Staying"  
"It's Over" 


Since bursting onto the scene earlier this year, Sleep Theory have gone from strength to strength. With press coverage from American Songwriter, Billboard, Celebrity Access, Knotfest, and Loudwire, as well as major nods from SiriusXM's Octane, Sleep Theory have had a huge 2023 and are gearing up for an even bigger 2024. 

With Sleep Theory, the numbers don't lie. 
Rather, the stats tell an impressive story that continues to grow and evolve as the band heads towards the stratosphere. 
Sleep Theory's recent single "Numb" — watch the video here — follows the band's debut single "Another Way," which arrived in January 2023 and amassed 500k views on TikTok within 36 hours of release. "Gone or Staying" arrived next, and all three songs combined have generated over 25 million streams, while "Numb" and "Another Way" both shot to No. 1 on SiriusXM's Octane Chart. The reaction was intense and swift, and as such, the band was also selected for SiriusXM/Pandora's Artist Accelerator Program and will be a part of their Next Wave Concert Series this fall. Additionally, "Numb" rose to No. 1 on Octane's BigUns four (!!!) times. 
This all happened in the span of the past nine months. 
 But what seemed like an overnight success (or an "industry plant" playing to the algorithm, as some trolls have incorrectly theorized) has actually been years in the making. And it's paying off. 
Since retiring from the U.S. Army several years ago, Moore has dedicated his life to carving his own path in the music industry. 
Officially starting Sleep Theory in 2019, the current incarnation of his musical journey began as a studio project to fuse his love of hard rock, funk, and R&B. 

Now a four-piece band, which came to be on the back of a chance meeting via Facebook Marketplace, Sleep Theory have achieved a pair of No. 1 singles, played their first run of shows to massive crowds, and signed to Epitaph Records. Combining metalcore-like breakdowns with bluesy grooves and a pop sensibility made for modern radio, "Numb" has ascended to the No. 19 position on the Active Rock chart. 
Sleep Theory wrapped summer touring runs with Set It Off and Shinedown, and also played shows with I Prevail, Badflower, and more. 
Their 2024 touring plans are extensive and will be announced soon!
