Lately I have been recording hours worth of riding the tube and trying catch interesting conversation, and occasionally interviewing individuals for their opinion of the Underground system. The goal right now is for a 30 minute sound documentary of the tube. I was fortunate to be able to talk to a busker who was playing right outside of the Hammersmith station, and therefor outside the boundary where I am not allowed to interview. For any film or photography the tube officials have to grant permission as well as collect a fee. I have not paid the fee or received permission to be documenting the tube but the rules do state anything about sound recordings. Still, I am collecting my sounds somewhat discretely.
