A young Quakers group in Nottingham, England released this 30-minute podcast of a silent meeting, complete with the ambient room sounds. John Cage would be proud. From The Guardian:
Quakerism was founded in the 17th century by the dissenter George Fox during the years of Puritan England. The group's meetings are characterised by silence, which is occasionally broken when someone present feels the urge to speak, say a prayer or offer a reading.
The idea for the silent podcast first came from Tim Gee, a Quaker living in London, who was inspired by the BBC's season of "slow" radio, which treated audiences to – among other things – the sounds of birds singing, mountain climbing and monks chatting.
Gee said he had wanted to "share a small oasis of calm, and a way to provide a moment of stillness, for people on the move".
