Celebrated Argentine-Israeli conductor Daniel Barenboim will direct a concert in honour of United Nations Secretary General Kofi Annan Annan, who will leave his post at the end of the month (DEC06) after two consecutive five-year terms, will have an orchestra play works by MOZART and BRAHMS for him. Argentine-born Barenboim made his musical debut in Rome in 1952 as a pianist, before becoming a conductor. He has directed the Berlin Opera since 2000, and also directs the Chicago Symphony Orchestra.
