Bam! Bach's Matthäus Passion is an explosive spectacle with many wow moments, according to the boys of the Hague Matrozenkoor. The collaboration between the Residentie Orkest and the Haags Matrozenkoor has existed since 1935, which makes it extra special. For the boys it is great to make music on a professional level. Making music together is fascinating and can move people to tears. We took a look behind the scenes at one of the rehearsals.
