Mass in Memoria is an improvisational piece by Emily Burridge created from the sonic acoustics of the structure of the Sacristy of Chartres Cathedral, France. The work is part of the Meditations Collection and it was recorded in July 2016 from Burridge’s performance as part of a memorial mass for the victims of the tragedy in Nice. The service was being relayed via a small speaker to the Sacristy, where the bishop sang responses, whilst Burridge improvised a live cello set, influenced by the harmonious discourse.
