Plastic Ono Band is a band concept announced by John Lennon and Yoko Ono in 1969 before the dissolution of the Beatles.
Lennon and Ono had begun a personal and artistic relationship in 1968 by collaborating on the experimental album Unfinished Music No.1: Two Virgins. After a second volume, Unfinished Music No.2: Life with the Lions appeared in the spring of 1969, they decided that all of their future endeavors would be credited to a conceptual and collaborative vehicle, 'Plastic Ono Band'.
As the project progressed, the name came to represent a succession of collaborations, by Lennon and Ono singly or together, with a host of artists including one performance line-up comprising Klaus Voormann, Yes drummer Alan White, and Eric Clapton, and other studio and performance groupings of artists such as George Harrison, Delaney & Bonnie and Friends, the Who's drummer Keith Moon, New York band Elephant's Memory, Billy Preston, Nicky Hopkins, Phil Spector, drummer Jim Keltner.
In revival since 2009 with Sean Lennon, Cornelius, Yuka Honda, a host of new collaborations has occurred with artists including Kim Gordon, Thurston Moore, Bette Midler, Lady Gaga, Mark Ronson, Scissor Sisters, Harper Simon, Paul Simon, and Gene Ween.
