The group consisted of Anders "Flanders" Molin (accordion, music box), Martin "MacGyver" Molin (glockenspiel, traktofon, toy piano, Theremin), Jon Nils Emanuel Ekström (drums, sound box, small bells), and later on, Marcus Sjöberg (drums).

The three members grew up in the city of Karlstad, Sweden, located in Värmland County, but they did not form a band until they had moved to Gothenburg in 2005.

[1] The usage of more unusual instruments such as the accordion was inspired both by its prominent use in the soundtrack for Amélie as well as musical traditions in Värmland.

[2][3] Between 2006 and 2008 the band toured extensively and also participated in several Swedish radio and TV shows including a program at MTV Europe.

In August 2010, the band was dissolved and clearly stated on their official website that they would not make any more music or live performances under the name Detektivbyrån.
