The Dutch Hammond organ player Rob Mostert develops, in cooperation with DJAZZ, the programme 'Mostert Meets'. In this series, the Hammond B3 organ takes centre stage. Rob Mostert invites the world's finest jazz musicians for a musical collaboration, in which the Hammond Organ plays a major role. The Hammond B3 is an electric organ, which generates sound by creating an electric current from rotating a metal tonewheel near an electromagnetic pickup. Initially, the Hammond B3 was at home in churches, until it entered the jazz scene in the mid-20th century. In this episode, Mostert performs with his band 'The Preacher Men', consisting of saxophonist Efraim Trujillo, drummer Chris Strik, and of course Hammon organist Rob Mostert himself!
