Derango are Jens Eriksson and Ola Eriksson originally from Örebro, Sweden but now living in Malmö. Even though they have the same surname they are not related. They make so-called "forest music" (a sub genre of psychedelic trance). This is hyper psychedelic music and they are one of the top acts in this emerging genre. Derango had numerous releases before their debut album "Tumult" was released on Inpsyde Media in 2005.
