2010 release. Tully Potter writes: Had they never met, Adolf Busch (1891-1952) and Rudolf Serkin (1903-1991) would still be regarded as two of the greatest musicians of the 20th century. But together they formed something extraordinary, even among the various marvellous ensembles organised by Busch. When they did meet, at the Vienna apartment of mutual friends in 1920, Serkin was only 17 and Busch at 29 was already the most famous German violinist, playing the classics, while his junior had been champioing the avant-garde movements of his time. They were of different backgrounds, but the lad was ready for a change back to the mainstream and he and Busch hit it off straight away. He became almost a son to Adolf and Frieda Busch, lived in their various houses and in 1935 married their daughter Irene.
