Raised in Bristol, Jack Wallis’ earliest musical influences were shaped by dubstep, punk, and UK techno, shown by his early releases on Darwin’s label SPE:C. Following his move to Berlin in 2017, he and The Lady Machine established Unterwegs, an imprint to release music from like-minded talents, including Decka's pressurized, raw, and driving techno productions. Since then, he has released on top-tier labels such as KEY Vinyl, AMTK+, Token, Tar Hallow and Reclaim Your City. Pushing the boundaries of modern-day techno, the quality of his music is consistently recognized with multiple sold-out releases and a growing portfolio of remix commissions for esteemed artists such as Dubfire. He now runs a second label with artist Roseen - Frameworks - where the duo released their debut album “Imaginary Places” in 2023. His fervent love for analog in the studio translates behind decks. DJ’ing only with vinyl since the beginning of his career, Decka’s sets not only highlight his clear-cut technique but are filled with moments of suspense and tension amidst high-octane energy, drawing on his extensive knowledge of techno, never limiting himself to just one style.
