Pianist Michael Abramovich plays Frédéric Chopin’s Nocturne Op.9 No.2 on a floating ponton on the river Elbe in front of Hamburg’s famous concert hall Elbphilharmonie. While he plays, activists project a heart shaped earth and the slogan „Planet Earth First“ onto the landmark building. The activity is organized few weeks before the G20 summit taking place in Hamburg, to ask political leaders to act for the protection of the climate.
