Reinholdtsen graduated from the Norwegian Academy of Music where he subsequently completed his diploma degree in composition.
Reinholdtsen’s first pieces were modernistic, complex works in the German style, of which the best known is perhaps Psalm (Narrative Studies) for sinfonietta recorded on the album Faces (2000).
He has also distinguished himself as a singer in the ensemble Nordic Voices, and is active as a culture critic and commentator.
[1] Since his debut, Reinholdtsen’s music has developed in a performative direction; conventional music passages are fused with performance-based forms of expression including essayistic interpretations, live-camera filming and elements including statistical facts, and face-making.
