This 30-part Radio 4 series explores how our interactions with sound have shaped us over 100,000 years. These specially extended episodes, recorded on location around the world and in collaboration with curators of the British Library Sound Archive, take us from prehistory to the present, encompassing the shamanistic music of our cave-dwelling ancestors, the massacre of noisy cats in pre-revolutionary Paris, the nerve-destroying din of trench warfare, right through to the cacophony of the modern metropolis. This is sound as life and death, pleasure and pain, power and revolution.

Written and presented by Professor David Hendy from the University of Sussex. Produced by Matt Thompson for Rockethouse Productions. Theme tune composed by Joe Acheson from Hidden Orchestra. Readings Director Cherry Cookson. Assistant Producer - Cathy FitzGerald Includes a specially-composed 15-minute companion piece by electronic musician Matthew Herbert in which he retells the story of the whole series using only the sounds themselves.
