Simon Rattle
He gave his first concert as principal conductor of the BPO on 7 September 2002, leading performances of Thomas Adès' Asyla and Gustav Mahler's Symphony No. 5.  He has done many new things since working in Berlin.  He has continued to conduct the music of many living British composers.  He has formed an educational programme so that young people in Berlin get used to hearing classical music.  Some people have criticised what Rattle has done in Berlin, but many people support him.
