Eric Prydz (or Cirez D) is a DJ, producer and label manager from Stockholm, Sweden. He runs the labels Pryda Recordings, Pryda Friends, and Mouseville Records.
He uses the alias Cirez D and his Mouseville imprint for his more underground techno and electro productions.
In an interview with the swedish national radio P3, Prydz told his Cirez D alias started with the track "Teaser", which he produced as a joke between his friends in response to how uninteresting he thought the progressive genre was. Nevertheless, the track got a great response which enabled him to continue to produce under his alternate alias.
