A concert for toy piano and cello? This curious combo is very rarely seen on concert stages. South African cellist Wilma Pistorius and Australian pianist Anne Veinberg are both active in the Netherlands. Together they created an intimate concert experience for the tiny toy piano and the indestructible cello. The focus is on Secret Compartment, an interactive work for toy pianos and music box by composer and cellist Wilma Pistorius.
