The organ of De Thomas exists 50 years. It will be celebrated during this year with special concerts. On Sunday 27 November they will kick off the anniversary year with a very special performance of Simeon ten Holt’s world-famous Canto Ostinato. In the beautiful church hall, organist Aart Bergwerff plays the Van Vulpen organ together with pianist Jeroen van Veen. Both have an enormous track record and play the Canto Ostinato with great regularity. With an introduction by Harmen Trimp, permanent organist of De Thomas.
