At the turn of the century, the number of homeless in Manhattan increased enormously. A group of them disappeared underground, into the tunnels below the city, and war photographer and cultural anthropologist Teun Voeten went with them. For months, he lived with Vietnam veterans, macrobiotic hippies, junkies, misunderstood philosophers and computer programmers. Tunnel People was a wonderful record of an underground society. Not long after, the 'residents' were chased out, but railway company Amtrak offered them alternative accommodation. Thirteen years later, for the new version of his book, Voeten revisited the tunnel people and photographed their lives above ground.
