Eidola is an American rock band from Spanish Fork, Utah, formed in 2011. The band consists of lead vocalist, composer and multi-instrumentalist Andrew Wells, guitarist Sergio Medina, bassist Reese Ortenberg, guitarist and unclean vocalist Matthew Dommer, guitarist Skylar Caporicci, and drummer Matthew Hansen.

Nerv is a 4-piece genre-bending rock band currently located in California. Nerv is Dillon Jones (Vocals) Scott Buchanan (Guitar/Vocals) Jordan Grokett (Guitar) and Tyler Clark (Drums). Nerv burst onto the scene in November 2017 with their heavy hitting debut single ‘Enough’. Then in Spring 2018 the band released their highly successful debut EP 'Bad Habits’, working with producer Erik Ron (Godsmack, I Prevail, Hollywood Undead). In October of 2022, Nerv released their long-awaited debut full length album, 'We're All Patients Here'. Now in 2025, working with producer Matt Good (Asking Alexandria, Hollywood Undead, Ice Nine Kills), Nerv is launching a new sound with their EP, ‘LOST!’

Astronoid is a post-metal band from Lowell, Massachusetts, formed in 2012. Started by vocalist Brett Boland and bassist Daniel Schwartz, the current lineup includes Boland, Schwartz, guitarist Casey Aylward, and drummer Matt St. Jean.
Creation should feel like a moment of self-actualization. Full potential and promise become fulfilled, and the next step can be taken. Astronoid reach such a moment on their self-titled second album. The Boston quartet—Brett Boland, Daniel Schwartz, Casey Aylward and Matt St. Jean—actualize the scope of their dynamic and dreamy deluge of thrashing guitars, soaring shoegaze, progressive pummeling, and ethereal vocal emissions. The music reflects the ebb-and-flow of two years marked by intense life changes.
After making their introduction with the 2012 EP November and 2013 EP Stargazer, Astronoid arrived as an enthralling, engaging, and entrancing voice for heavy music on 2016’s full-length debut, Air. It graced year-end lists by Consequence of Sound, Stereogum, LA Weekly, Invisible Oranges, Loudwire, No Clean Singing, and more. In addition to acclaim from Noisey, MetalSucks proclaimed it “an instant classic.”
In the end, Astronoid embrace a newfound confidence and bring listeners closer than ever.
“There’s a lot more of us in this record,” he leaves off. “It’s super personal. It gave me the affirmation I needed that I can still write music and that it’s not about besting what you’ve done in the past, but rather being who you are. That’s what it gave me. I hope it aligns with something a listener may need.”
