Joost Geevers is a remarkably versatile musician. As a conductor, trombonist, actor in musical theatre, teacher, and philosopher, his mission is to share the richness and depth that music has to offer with a wide and diverse audience.
As a guest conductor, Joost has worked with leading ensembles such as the Residentie Orkest The Hague, the National Ballet Orchestra, the South Netherlands Philharmonic, the North Netherlands Orchestra, the Phion Symphony orchestra and the Metropole Orchestra, among others.
In 2008–2009 he served as conductor of the Ligeti Academy of the Asko|Schönberg Ensemble, and ever since he has been an active advocate for new music both in the Netherlands and abroad. He led the Dutch premieres of Charles Ives’ Universe Symphony with the North Netherlands Orchestra and Karlheinz Stockhausen’s Hochzeiten from Sonntag aus Licht with the Radio Philharmonic Orchestra. Joost has also collaborated with the Netherlands Wind Ensemble, Ensemble Klang, Orkest de Ereprijs, HIIIT, the Ives Ensemble, and the Aarhus Sinfonietta.
Equally at home in light music, Joost has conducted concerts and recorded albums with artists such as Di-rect, Fay Claassen, Sven Figee, Trijntje Oosterhuis, Anneke van Giersbergen, Blaudzun, Fresku, and De Kast.
As a trombonist, he has performed with the Residentie Orkest The Hague, the North Netherlands Orchestra, the National Ballet Orchestra, Phion, the Radio Philharmonic Orchestra, the Asko|Schönberg Ensemble, and Rotterdam Sinfonia. He is also co-founder and performer with the contemporary music theatre collective Neo-Fanfare 9×13, and has appeared as a musician-actor in productions by the Dutch National Opera, the North Netherlands Theatre, and Club Guy & Roni. Always seeking to expand the boundaries of performance practice, Joost collaborates regularly with ensembles such as Pynarello and Club Classique.
In addition to his musical work, Joost studied philosophy at the University of Antwerp. He frequently writes and lectures on the intersections of art and philosophy and is a member of the research group ‘Music, Education and Society’ at the Royal Conservatory in The Hague. He is the author of two books on performance practice — In Conversation with the Old Masters (2015) and Bach is Not a Genius (2025). Since 2016, he has been teaching at both the Royal Conservatory in The Hague and the Codarts Conservatory in Rotterdam.
