An eyewitness, Maria Etzel, has sent me this account of the disturbance, by a single audience member, during a Bruckner concert at the South Bank:
Last night at the RFH,
halfway through Bruckner 4 when the music was really quiet I heard
sounds of male voices coming from the choir section. Was very
intrigued and then I saw this tall man leaving the choir secion and
walking towards the exit. It is a long walk from the choir to the exit
on level 4 and all the time shouting Terrible. I think he must have
said more when still in the choir section but was unable to
understand. It was quite a disturbance and he managed to completely
break the spell of the performance. Questions: A lunatic? a grudge
against LPO? or Osmo Vänska? or disliked the Bruckner? who knows.
Others have told me that there was no ushers present to remove the man from the hall. He was able to make his way at a leisurely pace, not to the nearest exit but to one that he preferred. I do hope the South Bank administration take measures to ensure the peace of their concerts in future. LATE EXTRA: You will find a full and frank confession from the disrupter here.
UPDATE: Here’s Erica Jeal’s measured account of the incident in the Guardian.
