Hans Marius Stormoen (February 7, 1943 – June 1, 2006) was a Norwegian bass player, philologist, and actor.
[2][3] Stormoen's interest in bass was aroused in Denmark, where he soon became acquainted with Niels-Henning Ørsted Pedersen, and then in Oslo's jazz and blues scene in the 1960s and 1970s.
He was part of Arild Wikstrøm's quartet (1961–1963) and in Jan Garbarek's first band, where he was named Norwegian jazz champion in 1963.
Stormoen was thus central to the environment at Club 7 (together with Bill Mulholland), from where he produced and participated in the 25-years album (MAI, 1988).
He also played in rhythm & blues bands such as Public Enemies, The Dream with Terje Rypdal, and Bryggerigangen Bluesband.
