The pianist was supposed to be playing Beethoven sonatas 24 to 28 in Tel Aviv, in a recital organised by the Israel Philharmonic Orchestra.
Without any announcement of a change of programme, he came on and played sonata 12, followed by 24 and 26, according to audience members.
The second half opened with the Waldstein sonata, followed by opus 109 and two Bach encores.
The Philharmonic management told Haaretz: This was a mistake on our part, arising from a misunderstanding. It’s won’t happen again.
