John Lennon/Plastic Ono Band is the debut studio album by English rock musician John Lennon. It was released in 1970, after Lennon had issued three experimental albums with Yoko Ono and Live Peace in Toronto 1969, a live performance in Toronto credited to the Plastic Ono Band. The album was recorded simultaneously with Ono's debut avant garde solo album, Yoko Ono/Plastic Ono Band, at Ascot Sound Studios and Abbey Road Studios using the same musicians and production team, and featured nearly identical cover artwork.
