Although she has been much maligned by Beatles fans and the UK’s music press, Yoko Ono is now recognised as a seminal artist and musician. She was introduced to the post-war musical avant-garde in the late 1950s through her first husband, who studied under John Cage. In 1969, she married John Lennon, and it was the beginning of a fruitful personal and musical partnership. Her influence has been acknowledged by The B52’s and Sonic Youth and can be heard in many other alternative bands of the last 30 years.
