A passion project from celebrated portrait photographer Perou with accompanying text from Karl Hyde of dance music duo Underworld, Tunnel Vision is a hypnotic portrait of England's underpasses. Photographed at night, you can almost hear the ominous hum of the broken strip-lighting, the knot of fear in the gut, the prickling silence of these desolate, urban landscapes. These unloved spaces are notoriously menacing, graffiti-ridden, inconvenient and prone to flooding. Yet through Perou's lens, the architecture is also elevated to something beyond itself, at times even ethereal.
