Four down, three to go: Le Balcon’s accomplished staging of Stockhausen's Licht cycle reaches its most problematic instalment.

The second day of aus LICHT is one mesmerising highlight after another, including the Netherlands Youth and Children’s Choirs in one magical and one sinister procession.

Part of a festival exploring technological innovations moving “beyond” the piano, Aufgang and Brandt Brauer Frick presented an evening of music in Paris that didn’t reinvent the instrument in quite the expected way.
