Coalescence was a collaboration between Soundlings, Insomnio, and Rosa Ensemble commissioned by Gaudeamus Muziekweek. It created a space and time where three generations of sound touched, pulled, and fused. The resulting outcome was a concert program in which members of each organization formed three new constellations and performed new works specifically composed for the occasion.

Imagine a dark space with islands of light and sound. Small separate traces of sounds fly around hastily. At times, they illuminate the darkness, leaving bursts and flares of near-blinding light. Miscible as these elusive substances are, they sometimes touch each other unavoidably. With only the slightest contact, the streams are pulled together with an incredible force. Coalescence. Moving ahead along the same path for a while – tied together – then suddenly, all is blown to smithereens again.
