Performing as a permanent "piano duo" ensemble provides fulfilment and obligation in equal measure: it is a rewarding challenge because the two musicians must always seek the right balance and a suitable combination of skills that they can exhibit at one piano or on two identical instruments. "When we sit at two pianos, we cannot see the other's hands, and when we sit at the same piano, we cannot see each other's face – none of that is necessary. We have a sort of body sensitivity that helps us to communicate with one another on a sub-conscious level and to inspire each other."
