Once and for all: Furtwängler showed an interest in the music of his time, particularly that of young composers. He recognised the talent of Austrian composer Theodor Berger (born in 1905) at a very early stage.
This is how he came to premiere and perform one of his most frequently played pieces, Rondino giocoso. Here is the PDF file of the Berlin Philharmonic concert programme for 15–17 December 1940, which features the Berlin premiere of this work.
