The invocation sung at the start is called Cloudsong: it is the rain falling, feeding the river, which springs to life and flows through the land and out to sea. There, the cloud reforms and returns to the land, nourishing, renewing and refreshing it. The constant refrain ‘uisce beatha’ translates as ‘water of life’. The number builds from the gentle song to the dancers’ feet rhythmically recalling a river gathering force and rushing to the sea.
