De/Vision is a German synthpop musical group. The band started as a quartet consisting of Thomas Adam, Steffen Keth, Stefan Blender, and Markus Ganssert. They formed the band in 1988. The name De/Vision is a play on words. The majority of the band's lyrics are in English, but they have had some songs in German.
Markus left the band in 2000. In the same year Steffen started a side project as the vocalists with Green Court, called 'Green Court featuring De/Vision'. The band with remaining members Thomas Adam and Steffen Keth were then signed to Drakkar Records and Sony BMG in Europe, and Dancing Ferret Discs in North America. The band is currently signed to Metropolis Records in North America. Since 1994 the band has released a new studio album of original material roughly every 1.5 years, until their latest album Rockets and Swords.
