The churches of Haarlem in association with the Gitaarlem foundation asked me to compose and perform a piece to celebrate the 500th anniversary of Luther’s reformation. I tried to connect and combine bits of Dutch musical culture in a contemporary folk piece. It consists of three parts. We will perform it in the Grote Kerk in Haarlem, with the full album band, three additional singers and Noortje Braat conducting. The old Müller pipe organ (1738) will be played too, by Anton Pauw, organ player for the City of Haarlem.
