He is best known for his series of albums setting to music the lyrics of William Blake, W. B. Yeats and Olav H. Hauge.
Coren's first album The Echoing Green comprised songs written and composed by him, though the title was taken from Blake.
His next project, Lovecloud, was dedicated to his heroes, Blake, Yeats and John Lennon, but the songs were written by Coren himself.
In 2008, Coren returned with a double-album setting to music the lyrics of the Norwegian poet Olav H. Hauge.
I draumar fær du was Coren's first album in Norwegian, and the first part of a series devoted to Nordic poets.
