Seizing the Little House Arena at Latitude, Christopher Brett-Bailey’s latest show gets off to a rocky start. Running almost half an hour late (in what has otherwise been a very tightly orchestrated festival), the audience wait confusedly outside. Eventually, we are admitted inside and Christopher explains the problem. His show is designed to be played at 120 decibels; at that volume, you would be able to hear it at all other stages on the Festival site: the organisers are having second thoughts. Before there is any time to really contemplate this, a steward marches through the crowd hurling neon ear plugs and Christopher proudly declares that they are going to do it anyway until “the Narcs shut us down”.
