On a sunny friday afternoon I find myself in a lively street in the center part of Prenzlauer Berg in Berlin. The Dutch musician Rik Spann and today’s interview partner Stephen Nachmanovitch are at my side. Stephen came here to give one of his popular improvisation workshops. Rik and I are two of the participants. None of us know that area of Berlin so we decide to go to an Italian restaurant just a few steps away; artists need to eat as well.
