Detektivbyrån was a Swedish electronica and folk music trio from Karlstad. The group consisted of Anders "Flanders" Molin, Martin "MacGyver" Molin, Jon Nils Emanuel Ekström, and later on, Marcus Sjöberg.
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. 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. As the band also played as street musicians there was originally also a requirement to have portable instruments such as the glockenspiel.
Between 2006 and 2008 the band toured extensively and also participated in several Swedish radio and TV shows including a program at MTV Europe.
On 3 September 2008 Detektivbyrån released their first full-length album, Wermland. The band was nominated for two Grammis awards, as newcomer of the year and folk music of the year in 2009. In addition they were also nominated for an award at Manifestgalan as the best live act of 2008.
