Real places that light up

Underground — a rave in a railway tunnel

A rave in a disused railway tunnel, its LED tubes rushing toward you.

What Underground shows

Underground is built from two photographs of the same abandoned tunnel, LED tubes off and then on. All the tubes at the same depth light up together to form a ring, and the moving ring makes you feel you are racing down the tunnel.

The camera never moves: it is the light that swallows the space, at the speed of the tempo. A raw, fast world for techno, hard techno, EBM and drum and bass.
