The second instalment of the BMW Tate Live series, where new performance works are made specifically to be streamed live online. This time, Pablo Bronstein takes over Tate Modern's Performance Room. An artist with a particular interest in architecture, Bronstein has made a number of works with dancers, looking at classical form, pattern and language. Here he'll be using ten dancers to create a baroque trompe l'oeil stage set that plays with perspective. Viewers around the world can post comments live during the performance.
