Mythos were a German band formed in Berlin by vocalist and multi-instrumentalist Stephan Kaske, bassist Harold Weiße and drummer Thomas Hildebrand in 1969. All high school dropouts, the self taught musicians released their eponymous debut in 1971. Influenced by Pink Floyd, Ash Ra Tempel and Hawkwind the album draws on science fiction and ecological themes particularly noticeable on the closing track "Encyclopdia Terrae". The release saw the band support Family, Colosseum and Humble Pie on tour, however after three year the band split.

Kaske then recruited Axel Brauer on drums and Michael Krantz on bass. The band wrote and played live for two years but failed to record and split up. On his own Kaske signed, as Mythos, to Cosmic Chorus, and recorded various TV and film soundtracks before recording DreamLab in 1975.

In 1976 Kaske expanded the lineup to include Sven Dohrow on guitars, Eberhard Seidler on bass and Ronnie Schreinzer on drums. The band adopted a heavier sound and released two albums, Quasar and Grand Prix. Kaske left the band in 1980 in order to concentrate on setting up his own recording studio in Berlin and pursue solo projects. Dohrow and Schreinzer formed The Twins, changing to a synth pop style and scoring a number of minor hits.
