For Surrey Unearthed, in collaboration with Mary Branson's LED light installation 'Harvest', The Calling heard tiny voices, like angels, singing in call and response at Boxhill. For this participatory performance, Morrigan led singers at the bottom of the hill and Anna Tabbush led singers at the top; calling to each other an extract from Vaughan Williams 'I Got Me Flowers' from 'Mystical Songs', adapted by Anna for the event.

The film was made by Ricardo Sanchez of Ricsblakes Films.
