Out documents a social era that seems so close and yet so far away: that wild, glamorous, disco-and-drugs-driven decade between the end of the Vietnam war and the advent of AIDS, when every night was a party night and such distinctions as uptown and downtown, gay and straight, black and white were momentarily cast aside. As the editor of Andy Warhol s Interview from 1971 to 1983, Bob Colacello was perfectly placed to record the scene, which he did in his monthly  Out column, a diary of the frenetic social life that took him from art openings to movie premieres, from cocktail parties to dinner parties, from charity balls to after-hours clubs, often all in the course of a single evening. Although Colacello started writing his column in 1973, it didn t occur to him to take his own pictures for it until two years later, when the Swiss art dealer Thomas Ammann gave him one of the first miniature 35-mm cameras to come on the market, a black plastic Minox small enough to hide in his jacket pocket. With their skewed angles, multilayered compositions, and arbitrary lighting effects, Colacello s pictures have an immediacy, a veracity, and an aesthetic not often found in the work of professional party photographers. He wasn t standing at the door pairing up celebrities and telling them to smile; he was in the middle of the action   an accidental photographer , he likes to say, catching his  subjects off-guard.
