The band Blood Harmony with the siblings from Svarfaðardalur was formed in the fateful year 2020. The band consists of the children of Örn-, Ösp- and Björk Eldjárn Kristjánsbörn and they perform original music in the spirit of Nordic and North American folk music. The band has performed in many parts of Iceland and abroad. This summer, the siblings have traveled around the south and plan to end the summer on the "home trails" on Græna Hattin on August 22.
