No matter the weather, jazz bassist Arnold Dooyeweerd has been cycling to the Bimhuis every Tuesday evening for the last forty-four years to give his famous jazz workshop. Everyone has a place onstage: jazz lovers, professionals, music students. There are hardly any jazz musicians in the Netherlands who haven’t been to this workshop. As always, the jamsession led by Jasper Blom starts at 22.00. Entrance is free. During CELLOFEST, instead of interrupting the tradition, the workshop and the jamsession are made to revolve around the cello, of course featuring Arnold Dooyeweerd. For the jamsession, Jasper Blom clears the stage for cellists Emile Visser and Annie Tangberg.
