Sometimes, there's something extraordinary hidden in a simple gesture. In Alain Platel's Ombra, this becomes quite literal. Guided by language coach Bart Verheyden, our choir and ballet set to work to learn Handel's aria Ombra mai fu into sign language.

Bart beams with pride: 'It is amazing how quickly the dancers pick up the gestures and the choir is proud that they can also perform in this new language.'
