We saw the Creole Choir of Cuba last week at the shortly to close Clocktower in Croydon

Bloody outstanding in Brighton. At one point the six women came to the front of the stage all caught one another's eyes and then all six launched together in harmony into a song without anyone being given a note. How do they do that? The shifting pattern of their harmonies between the ten members was quite outstanding. They displayed a level of musicality that the aforementioned acoustic pop group - or 99% of those active on the British folk scene for that matter - could not hope to match.
