Started by Audun Storset and Marcus Forsgren, the Lionheart Brothers released their first EP Colour Contrast Context in 2004, on Norwegian label ChewinPine Records. By this time Audun and Marcus had decided to recruit two more members : Frantz Andreassen and Peter Rudolfsen and toured Norway intensively.

In January 2007 The Lionheart Brothers released Dizzy Kiss in Norway which got great review and made n°14 on the national top 40 charts! Musically ambitious, they intend to force it on the rest of the world.
