Musician, composer and producer
I am a professional musician on electric and acoustic bass living in Bergen, Norway.
I completed my education at Jazzlinja, which is part of the Trøndelag Music Conservatory (now known as the Institute of Music at NTNU), during the years 1996 to 1999.
Since then, I’ve performed in numerous concerts and different types of shows.
Mostly in Norway, but also in Denmark, Finland, Estonia, Russia, Lithuania, Germany, Switzerland, Italy, Czech republic, Slovenia, Ireland, Scotland, USA and Canada.
I am both an artist with my own band, and a versatile freelance musician working with jazz, pop, rock, folk and other genres. I have done a lot of theater work on musicals and various other plays.
I also write and produce music for my own quartet and for other projects. My own music is a kind of contemporary jazz. I have released three albums as an artist and I'm currently working on the next one.
Ole Marius Sandberg quartet - an ongoing project started in 2013.
New album release - Via Saracco - 29.08.2025 on digital streaming platforms. We went into a location studio in the beginning of march and recorded the compositions for my upcoming fourth album. It is now finished and released on (almost) all the major streaming services and at Bandcamp.com.
Other things in 2025:
The project Resonans with vocal ensemble Volve vokal where I both composed and played bass. We did some concerts with this music on USF, Bergen in september/october. This was made possible with an artist grant I got from Vestland County.
