Cancellation Notice:

Over the past few days the RNCM has received a significant amount of negative correspondence relating to the booking of Gilad Atzmon and the Orient House Ensemble on Thursday 5 March.

After careful consideration, and to ensure the safety of all involved, the RNCM decided to withdraw the concert. This decision was taken and actioned prior to the launch of an associated petition and in no way reflects any political view of the College. We apologise for any inconvenience caused.
