Shoe maker Palladium put together this very nicely done documentary that looks at London Pirate Radio.
About the documentary, Palladium says:
Pirate radio is everywhere in London, born in the 60’s from rusting anti-aircraft towers in the mouth of the Thames. Today’s broadcasts are hidden in plain sight, transmitting from secret tower block studios via homemade rooftop antennas. We put our boots on and went exploring.
London Pirate Radio is the sixth in Palladium's Exploration series.
