National and international jazz musicians were invited to the NDR for the Jazz Workshop series. A number of ten to twenty musicians could rehearse for some days and finally present their results to the North German listeners in a live studio concert. The organizer focused on offering some space for experimenting to different musicians who otherwise would never have played together. The focus was on modern jazz, especially on bebop, hardbop and cool jazz. This was later completed by some new styles such as fusion, jazz rock and world music. Recorded April 13, 1962 in Hamburg, Germany. Features Conny Jackel (trumpet), Christian Kellens (trombone, horn), Rolf Kühn (clarinet), Bernd Rabe (alt sax, bas), Poldi Klein (tenor sax), Horst Jankowski (piano), Attila Zoller (guitar), Götz Wendland (bass) and Kurt Bong (drums).
