Collective Hum: A short film exploring the polyphony of collectivity in the desires, motivations and stories that foreground the histories and present(s) of Black British sound. Collective Hum documents a collective in practice through the operation of B.O.S.S using multiple narration, overlapping voices and the sound of group interviews, meetings and events to create a polyphonic score to soundtrack images of the ‘collective bodies, kinaesthetic experience and gestural language’ of sound system culture.
