Iconic rock group Pink Floyd is one of the few bands who wholly encompasses the rebellious but philosophical mood of the 1960s and 70s, yet is still influential and relevant today. The English band was formed by Nick Mason and Roger Waters, who were both architecture students at the Regent Street Polytechnic in London. They played with other members until 1965, when after a juggling of drop-outs, Air Force postings and new members, The Pink Floyd Sound was formed and became the resident band at the Countdown Club in London.
