The show was freaking awesome start to finish. Mourning Eve was excellent especially for their first ever tour. The energy and overall musicianship was great for such a young band. Oxymorrons, the energy and personality while literally getting everyone in the audience involved and moving. They set the stage for what was to come and if they are ever coming back to Seattle, I'm definitely seeing them again. Nevertel killed it and kept the energy going throughout the whole set. They really went in hard and the drummer hits so hard with the vocals being so freaking good. Sleep Theory was extremely excellent and throughout the show they were attentive to the audience because the venue was really hot and they were making sure those that needed water or help, moved to a safe spot. The performance basically always 1 1/2 hours long and made every bit of it and experience. I'm so glad to have this opportunity to see them because when they eventually blow up, seeing them in such an intimate venue will be very hard to come by. Definitely keeping an eye out for all these bands.

Sleep Theory Biography
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.
