Dan and Karl met in Gothenburg during the early 1970s when they played in groups Älgarnas Trädgård and Anna Själv Tredje.

The group have consistently used synthesizers and electronic effects to create their theatrical and atmospheric soundscapes, and from 1984 they began to work with samplers.

[3] In the early 1990s, Twice a Man created a side-project entitled The Butterfly Effect, an experimental electronic project which installed writer Zac O' Yeah as light designer and Peter Davidson as musician and singer, releasing the album Trip in 1991.

[4] They later continued as Twice a Man, but during the decade they decreased their production of studio albums and tours to concentrate on project-based work, often in collaboration with theatre, visual artists or companies.

Recent works by Twice a Man include the album, Icicles, released in April 2010,[5] as well as a 50-minute ambient CD, Costume Area, which was released to coincide with the opening of a Charles Koroly exhibition at the Dansmuseet museum in Stockholm, for which they provided music and sound design.
