In a certain respect, the enthusiasm that Jan Dokter shows while on stage conceals a musical career for over many decades. As a genuine entertainer he underlines the current orientation of the CTJB, which might be characterized as being focused on the audience with a repertoire of various styles. As a player of the clarinet, sax, trumpet and well-known as a vocalist, Syndey Bechet and Bix Beiderbecke became Jan’s leading models of jazz. Particularly, his former music teacher brought Beiderbecke to Jan’s attention.
