DOCUMENTARY PREMIERE: Michael Epstein, who directed 2010’s LennoNYC for PBS’s American Masters, finds more inspiration in yet another chapter from the former Beatle’s years as a resident artist in New York. This documentary takes a long, detailed look into the content and recording of John Lennon’s Imagine album in 1971, and also into his personal and creative life with Yoko Ono during the same period. For fans of this artist, this couple, this album, and the sentiment of its title song, I can’t Imagine them wanting to miss it.
