Konrad Koselleck, born in Heidelberg in 1971, is one of the leading arrangers in the Netherlands. Trained as a pianist at the Hilversum Conservatory and as a composer and arranger at the Amsterdamse Hogeschool voor de Kunsten, his artistic roots lie in jazz. His musical spectrum ranges from classical to avant-garde, hard rock and dance music to folk music from all over the world, regularly and consistently crossing the boundaries between serious and popular music.
His arrangements and compositions have been created for numerous renowned ensembles in jazz, classical music and cross-over music and have been heard from Cairo to New York’s Carnegie Hall. The Konrad Koselleck Big Band, which plays exclusively arrangements and compositions from his pen, has made a name for itself since 2004 as an orchestra which, in addition to regular jazz concerts, also performs theatre shows with well-known chansoniers and entertainers, including Pierre Kartner alias Vader Abraham.
Konrad Koselleck has written various soundtracks for film and television and has worked with and for actress and singer Ellen ten Damme, big band luminary Peter Herbolzheimer, contemporary music specialist Claron McFadden, jazz and pop legend Greetje Kauffeld as well as for the Jazz Orchestra of the Concertgebouw and the Nederlands Blazers Ensemble. Various recordings document his work.
After teaching at the Amsterdamse Theater Academie and the Amsterdam jazz school DJAM, he has been teaching arranging and composition at the Utrecht Conservatory since 2015. In 2022, he provided jazz arrangements for Kirill Serebrennikov’s production of »Der Freischütz« at the Nationale Opera Amsterdam with the Royal Concertgebouw Orchestra. In 2024, he composed the music for the tap dance performance »100 Leidenschaften« for the Staatsoperette Dresden.
Together with Thomas Pigor, Konrad Koselleck wrote the jazz musical »Roulette«, which premiered at the Saarländisches Staatstheater Saarbrücken in 2010, as well as the operettas »Drei Männer im Schnee« (2019) and »Oh! Oh! Amelio!« (2024) for the Gärtnerplatztheater.
