Niek de Groot & Catherine Klipfel French Connection / During the two decades Catherine Klipfel and Niek de Groot have been playing together, they have often focused on the French repertoire; a shared love. Catherine is French and Niek has many musical roots in France. Within this repertoire the color spectrum of the double bass together with the richness of the piano create new timbres and open new horizons. The idea of making an album with a complete French repertoire therefore seemed like a logical idiomatic step.
