In Plac Wolnosci (Freedom Square), Finnish violinist virtuoso Pekka Kuusisto and the renowned Britten Sinfonia perform at Greenpeace's 'Concert for the Climate', playing Vivaldi's Four Seasons intermingled with Argentinean composer Astor Piazzolla's Four Seasons of Buenos Aires. The event was staged in Greenpeace's giant Climate Rescue Station; a huge geodesic dome, which was brought to Poznan to inspire politicians to take action against global warming.
