Many musicians consider Jean-François Jenny-Clark to be one of the greatest bass players of his generation, and I now realise that over the years and in many different projects and contexts, I was fortunate enough to share my rhythmic role with one of the greatest contemporary improvisers. Jean-François knew his instrument so well that he was able to assert his strong personality so quickly that it wasn’t always easy to adapt to his idea of tempo – it could be fragmented, loosely defined, deliberately variable or merely hinted at. His premature death makes one suspect that he never fully realised the importance of his personal contribution to music, nor the admiration we all felt for him. (Daniel Humair)
