Accessory is a German synthpop/electro-industrial group consisting of Dirk Steyer and Ivo Lottig.

The group began in 1994 when Dirk Steyer and Kay Resch formed a band under the name "Voices of Darkness", becoming "Accessory" in 1996.

In 1997 they released a demo album, Electronic Controlled Mind on a small record label named SD-IMAGE.

Shortly afterwards Kay left the band to pursue his own career, but returned in 2001 to do lighting and technical operations.

After the release of their second album, Titan, in 2003, Jukka Sandeck left the band to pursue an individual career.
