Imagine is the second solo studio album by English musician John Lennon, released on 9 September 1971 by Apple Records. Co-produced by Lennon, his wife Yoko Ono and Phil Spector, the album's elaborate sound contrasts the basic, small-group arrangements of his first album, John Lennon/Plastic Ono Band (1970), while the opening title track is widely considered to be his signature song.

John Winston Ono Lennon was an English singer, songwriter and musician. He gained worldwide fame as the founder, co-songwriter, co-lead vocalist and rhythm guitarist of the Beatles. His work included music, writing, drawings and film. His songwriting partnership with Paul McCartney remains the most successful in history.
