On 21 June 2010, Ljubljana celebrated Carlos Kleiber's 80th birthday with a concert by the Vienna Philharmonic directed by Kleiber's friend Riccardo Muti. "BBC Music Magazine" announced on 17 March 2011 that Kleiber had been selected as "the greatest conductor of all time." Some 100 current conductors, including Sir Colin Davis, Gustavo Dudamel, Valery Gergiev and Mariss Jansons, participated in the BBC poll. Kleiber, who conducted just 96 concerts and around 400 operatic performances in his 74 years, was voted ahead of Leonard Bernstein and Claudio Abbado, who took second and third places respectively.
