Daniel Barenboim will conduct the Berlin Philharmonic in a special concert, as one of many celebrations that will mark the event in Germany and around the world.
Commemorations began last week in the US with a visit from German Chancellor Angela Merkel, who spoke before an historic joint session of Congress on Tuesday, November 3, the first German leader to do so since Konrad Adenauer in 1957.

On the 9th, Merkel, Mikhail Gorbachev and Lech Walesa will walk together to the Bornholmer Bridge, where the first crossing was made. Their gesture will be purely symbolic, but the anniversary would be unthinkable without it, according to http://www.independent.co.uk/news/world/europe/a-bridge-opened-ndash-and-then-the-wall-fell-1817277.html
France will mark the occasion with an open-air concert and laser show held on the Place de la Concorde. According to The New York Times, the concert features prominent cellists from each of the European Union’s 27 member nations in a piece inspired by a musical tribute given at Checkpoint Charlie two days after its fall by cellist Mstislav Rostropovich.

Through a program called Maurreise, or Journey of the Wall, symbolic wall bricks have been sent to artists in Korea, Cyprus, Yemen, among other divided countries. Artists have been asked to incorporate these bricks into works expressing the pain of people separated by impenetrable borders.
