Arctic Dub (Sursumcorda) was a post-dub techno, ambient, and experimental music label, based in Porto, Portugal. Its origins arose from the deep influences of Basic Channel, echospace, and the early days of Deep Mix Moscow.
Founded by Dave Wesley, in 1998, in Minneapolis, Minnesota , as a sister label to Sursumcorda (label, magazine, and former Minneapolis nightclub), label headquarters has moved to Porto, Portugal, and expanded to include Gabi Von Dub, Casey Borchert, and graphic designer, André Macedo. It ceased its operations in 2020.
