During his entire career Sander van Marion is, in addition to being 
organist and cantor-organist of Bethel Church in Scheveningen, also 
very active as director.  

In the course of years, many LP and CD as well as TV recordings have 
been made under his direction.

The repertoire of the choirs is varied, comprising well known but also 
lesser known works. Familiar oratorios such as the ‘Schöpfung’ and 
the ‘Jahreszeiten’ by Joseph Haydn, the ‘Judas Maccabeus’, ‘Messiah’, 
and ‘Saul’ by Georg Friedrich Händel, the Weihnachtsoratorium by 
Johann Sebastian Bach, and major works by Mendelssohn, Mozart, 
Gounod, Saint Saëns and others all form part of the repertoire.
The performance of the oratorium ‘Samson’ by G.F. Händel was unique, as it featured the application of an opera-element through the use of decor, dress and scenery.

Less familiar works performed include the ‘Pastoral Messe’ by Anton Diabelli,  ‘Matthäus Passion’ by Georg Phillip Telemann, and the ‘Hirtenmesse’ by Jan Jacob Ryba.  The performances of these works were Dutch premieres.
Under his direction, the performances of ‘Dixit Dominus’ by Johann Christian Bach, and ‘Jauchzet ihr Himmel’ by Georg Phillip Telemann became world-premieres.  The manuscripts of these works, which Sander van Marion prepared for performance, were discovered by him in old libraries such as the Monastery of Einsiedeln in Switzerland and the Music Library in Berlin.
A European premiere that has several times been broadcast on television was the performance of the American Christmas cantata ‘The Promise of Christmas’, by Dan Burgess.

Sander van Marion also brought back from his concert tours in America other cantatas, i.e. musicals.  These have usually been performed by his choirs as Dutch or European premieres, and reflect his interest also in works of a modern or lighter genre.

With his male choirs, Sander van Marion turns to yet another musical inroad, with performances of selections from musicals, operetta and opera, and from various countries.  These include performances based on the themes ‘Rondom Walt Disney’, ‘Jubilate on Broadway’, ‘In Zuid Amerika sfeer’, ‘From Russia with Love’ and ‘Een klankrijk Millennium’.

In addition to his concerts in the Netherlands, Sander van Marion regularly undertakes with his choirs international concert tours to countries in Europe, but also to the USA and Canada.  Some of the highlights were concerts in famous cathedrals and concert halls in Salzburg, Prague, Berlin, London, Paris, Washington, Montreal, Toronto and Ottawa.
Other outstanding experiences were the concerts in the Concertgebouw in Amsterdam, directing the world’s largest male choir of 2,000 voices, and the singing by the Katwijks Christelijk Mannenkoor ‘Jubilate’ in Berlin, at the farewell of German Federal President Roman Herzog in Schloss Bellevue. 
Likewise, the performances in French cathedrals by C.O.V. ‘Cantate Deo’ from Zoetermeer, of the ‘Matthäus Passion’ by Georg Ph. Telemann. 

Also worth mentioning are the concerts with many vocal and instrumental soloists, in particular the performance by Princess Christina as soloist at one of the many Christmas concerts by Rijnlands Christelijk Mannenkoor ‘Vox Humana’, from Leiden.

These are all concerts that one remembers and that makes one realize how good and inspiring it is to make music together.
