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 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.
