Sølvguttene is a boys' choir founded by Torstein Grythe in June, 1940. He held the position as conductor until 2004, when Fredrik Otterstad took over. In 2019, Frikk Heide-Steen was hired as full-time conductor alongside Otterstad. The choir had its first rehearsals in Grythes apartment in Oslo, but were soon offered to rehearse in Norwegian Broadcasting’s facilities. The thought was that the choir would be permanently linked to NRK, and the first radio performance was held in December 1940. Conditions during the German occupation soon made it impossible to continue the cooperation with NRK, and the choir was for the remainder of the war years managed by the founder/conductor. Sølvguttene got its name primarily because of the shiny, silvery uniforms that were acquired in the beginning. Later the name has been attributed to the special sound and clarity of boys voices, voices of silver.
