Nidarosdomens guttekor, the Nidaros Cathedral Boys' Choir, is the oldest boys' choir in Norway, and represents a 900-year-long tradition of boy singers in the Nidaros Cathedral in Trondheim. The present choir was founded in 1927 in preparation for the 900th anniversary of the battle at Stiklestad in 1030, and celebrated its 75th anniversary in 2002. Professor Bjørn Moe of the Music Conservatory in Trondheim has been conductor and artistic manager for the choir since 1973.
During the last decade, the Nidaros Cathedral Boys' Choir has made 10 CD recordings and performed in numerous venues in Norway and abroad. It has sung for the Pope and all the European royal families. In February 2001 the choir sang at the exclusive International Boys' Choir Festival in Poznan, Poland. Its international status was confirmed in March 2001 when it was appointed as one of 15 European Culture Ambassadors by the Academy of European Choirs.
Princess Märtha Louise is patron of the choir.
In 2002 Norwegian broadcaster TV2 took up competition with Norsk rikskringkasting (NRK) on the boy choir front for the first time. Since 1965, NRK had shown its own choir Sølvguttene on television every Christmas. Thirty-seven years later, TV2 recorded one of Trondheim choir's Christmas concerts, and ran a documentary about its adventures. The productions were rerun the next year, but in 2004 a new made-for-TV concert was filmed in the picturesque, snow-covered exterior of the Trøndelag Folk Museum.
