 The album is notable because it was Lennon's fourth solo studio album and the first one he produced without help from Phil Spector. The reissue was overseen by Lennon's widow, Yoko Ono, along with their son, Sean Ono Lennon. Mind Gains, the ultimate collection, is available in multiple formats, including box sets, vinyl, CD, and Blu-ray. Tanya J. Powers, Fox News.
