Charlotte Moorman was a cellist who made her name by taking off her clothes in the interest of avant-garde music. She was most closely associated with John Cage and with the Korean composer Nam June Paik. In one work, she invited the audience to cut her clothes off, snip by snip.
Eager to be ahead of her time, Charlotte was altogether a Sixties person, a phenomenon not to be repeated.
When she died in 1991, we thought we had seen the last of her. But such as the wonder of social media that admirers and academics have created a Facebook site in her memory. Enjoy.
