The Shamen were an experimental acid house/techno band, initially formed in Aberdeen, Scotland by Colin Angus (b. 24 August, 1961), Derek McKenzie (b. 27 February, 1964), Keith McKenzie (b. 30 August, 1961) and Peter Stephenson (b. 1 March, 1962) in 1985 as a psychedelia-influenced indie rock act. They found underground credibility as an acid house act and a pioneer of the dance/rock crossover, before moving on to international commercial success with Ebeneezer Goode and the Boss Drum album.
