“Today marks a monumental moment in Sumerian and Periphery history,” says Sumerian Records’ Founder/CEO Ash Avildsen. “We’re incredibly proud of the progressive approach we took to releasing this body of music from such a progressive group of artists. I couldn’t be more elated about the synergy between Sumerian, Outerloop and Periphery in successfully executing the release of Juggernaut: Alpha & Omega. The band has a true cult following that appreciates their art and they just proved to the world that the Peripherals are only continuing to grow beyond boundaries. “

Periphery drummer Matt Halpern adds, “We are absolutely thrilled with the amount of positivity and excitement we’re seeing and receiving for the Juggernaut releases. As a band and as individuals we poured our hearts and souls into these releases, so to have this type of response is truly special. Thank you to those who have taken part in the Juggernaut experience so far… We can’t wait to play these songs live for you!”
