Greenland is a partnership between three Danish improvisors and David Thomas. It was formed by Jørgen Teller in 1996 as "Gefion Calls" for a one-off concert in the middle of Copenhagen's Gefion Fountain. Since then it toured Denmark in 1998 as Greenland.

This band later became known as David Thomas and foreigners.
