Starting off as a saxophone player and improvising musician, Espen's work and interest has diverged into music making and music production of different sorts, as heard on his solo albums Forgaflingspop and Nattsyntese. Using his own voice, lyrics and programming, these albums reflect his desire to bring musical elements together to form an unusual blend.
Playing saxophone is still one of his major occupations, and he can be heard contributing in renowned ensembles such as Streifenjunko, Christian Wallumrød Ensemble, Koboku Senju and Trondheim Jazz Orchestra. Awards include SpareBank 1 SMN JazZtipendiat, De Unges Lindemanpris, Spellemannsprisen (Norwegian Grammy) and Trondheim Jazzfestivals Talentpris.
