In Autumn 2012 Kathy Hinde became resident at Pervasive Media Studio, to compose a new vocal work that combined live singing with electronically altered voices. The piece was inspired by how bats Echo-locate by using sound to ‘see’ their surroundings and the project aimed to employ bio-mimicry as a creative method.  In collaboration with technologists, Kathy created a new device that used sensors and mini-computers. These devices effected the sounds of the singers voices based on where they were positioned in the performance space. A sonic and spacial experience. Technology was be developed by Matthew Olden and Tarim at the Pervasive Media Studio. The composition was developed with a Bedford Creative Arts' choir, and Mel McCree with the Bristol Feral Choir, and Kerry Andrew from vocal trio Juice. Specialist consultants on the project were Professor Gareth Jones, head of the Bat Ecology and Bioacoustics Lab at Bristol University, and Bob Cornes from Bedfordshire Bat Group. Vocal Migrations was commissioned by Bedford Creative Arts with additional funding from Arts Council England, and support in kind from the Pervasive Media Studio.
