Conductor Roger Norrington: Mozart's Symphony No. 40 What sets Norrington apart from other conductors? Well, hear for yourself. He is in Salzburg with Fred Child, sharing his fresh take on tempos, and underlying dance rhythms that must have startled old school conductors 20 years ago. Some shameless comparisons make his philosophy clear. Norrington conducts the London Classical Players in the slow movement of Mozart's Symphony No. 40 in G Minor, K. 550.
