Dún Aengus is a duo featuring Peter Andersson and Martin Rahmberg. The name of the duo is derived from a place on the small island of Inishmore on the west coast of Ireland, a place that holds a special meaning to the band members.

Dún Aengus has a comprehensive repertoire of Irish tunes and folk songs. They can also play quite a few Scottish songs and even modern pop songs if the situation calls for it.
