Above all, the Berliner Philharmoniker showed surprising sides of themselves that day: in unusual chamber music ensembles, master classes, and witty encores. Horn player Sarah Willis and star organist Cameron Carpenter went on an extraordinary expedition, exploring the organ of the Philharmonie from top to bottom. Chief conductor Sir Simon Rattle was also there of course, conducting an orchestra of ambitious – and excellent! – amateur musicians and a dance project from the Education Programme, choreographed by Sasha Waltz. Honorary guest of the day was Alfred Brendel: pianist and friend of the Berliner Philharmoniker for many years. At the Philharmonie, he read his own poems and officiated at the highlight of the day: the auction of the concert grand piano which he himself had played when performing with the Berliner Philharmoniker since 1992 and which now has found a new owner, with proceeds going to UNICEF’s emergency relief in East Africa.
