Ernst Glerum (Deventer, 20 April 1955) studies classical double bass at the Amsterdam Sweelinck Conservatory. In addition to his studies he dedicates himself to the performing practice of both improvised and composed music. The winner of the Boy Edgar Prijs (the major Dutch jazz award) is considered to be the ideal sideman. Many leading Dutch jazz groups, both present and past, employ his services as bassist, from the Instant Composers Pool to saxophonist Benjamin Herman’s quartet. Besides double bass he also plays piano in his own group Glerum Omnibus
