From A to B, easy as 1-2-3. I'm not gonna reveal the whereabouts of this tunnel, but it's more than 4 km long and run about 30-40 meter underground.
I'm fascinated by the workmanship of the complex construction, this is like going in to the core of modern urban culture, the veins of civilisation that gives life to people in the city above ground.
Theres no wind, no sound, no traffic, no hills. It's very quiet and peacefull in a slightly disturbing and post-apocalyptic way. The only sound from outside was the distant rumble from the Metro.
I went there with a good explorer friend and did the filming with a Canon A580 compact camera.
Music is an untitled track off the Cannibal Ox album "The Cold Vein". Their music fits well with my experience and the tunnel run like a huge concrete vein through the city.
