The pianist whose performance was cancelled by the Melbourne Symphony Orchestra says the organisation has taken a "nosedive" internationally following a protest during its performance at London's BBC Proms.
A group calling itself Jewish Artists for Palestine claimed responsibility for disrupting the MSO's performance at the Royal Albert Hall on Friday.
The concert was for a live BBC Radio 3 broadcast, but the music had to be stopped and the event restarted.
"The MSO has blood on its hands," yelled a woman in the crowd, in a video uploaded to social media. "You silenced Jayson Gillham! The MSO is complicit in genocide!"
