Daniel Barenboim is having trouble with his Buenos Aires compatriots.
His Brahms concert started at 8.20 because the audience were late to arrive.
They applauded between movements.
Barenboim stopped the music and asked for them to wait before clapping until the sound had died away. He also put in a request for no applause between movements.
The next time he stopped the concert was because people were taking phone pictures.
‘It hurts my eyes,’ he said.
