Concertkoor Haarlem was established in 1946 as Koor Katholiek Haarlem by the Haarlem organist and composer Albert de Klerk. He directed the choir 45 years and handed the conductorâ€™s baton in 1991 over to the current conductor Ger Vos.
In the history of the choir there were many successful performances of diverse choirworks of different composers (see repertoire). In 1995 the Concertkoor Haarlem participated with three other choirs at Concert Haarlem 750, on the occasion of the 750-years jubilee of Haarlem. In the year 2000 Concertkoor Haarlem performed â€˜Ein Deutsches Requiemâ€™ by Brahms. This piece requires large forces and was therefore performed together with the Toonkunstkoor Wageningen. A gorgeous experience to sing with 200 people on stage. In 2006 our choir existed 60 years, we celebrated this with an enormous jubilee concert of the â€˜Requiemâ€™ by Verdi, in cooperation with the Toonkunstkoor Wageningen.
