Arthur Cayzer, known as Pariah, is a British DJ and producer based in Amsterdam who has been active since the early 2010s. He emerged from London's club underground with early releases on R&S Records that established his eclectic approach to techno and house, drawing from post-dubstep, Detroit influences, and ambient textures. Since 2011, Cayzer has collaborated extensively with Jamie Roberts as Karenn, producing heavy, hardware-driven techno, and co-founded the Voam label in 2019 to release cutting-edge material from the project. His solo work and collaborative endeavors reflect a sustained engagement with the edges of electronic music across different spaces, from club floors to more experimental contexts. Pariah has performed regularly at Berghain and major European venues and festivals over more than a decade.
