On April 16, 1977, crowds of hip revelers cheered as nightclub Studio 54 first opened its doors at a building on 54th Street in New York City. These images capture the world's most famous nightclub Studio 54 during its 33-month existence, populated by celebrities such as Michael Jackson, Rod Stewart and Andy Warhol. The wild success of the '70s New York club has forever been put down to owner Steve Rubell's first rule of partying: 'The key to a good party is filling a room with guests more interesting than you.' By 1978, within a year of transforming it from a theatre to a nightclub, Studio 54 had made $7million and Rubell was quoted as saying 'only the Mafia made more money.' The space would later be adapted into a theater, but Studio 54's party scene in the 1970s and early 1980s will forever be remembered for its wild nights, high-profile guests, and massive crowds. Here's a collection of 100 amazing photos that will take you back nearly 40 years into the club. (via Flashbak)
