Overseen by
Yoko Ono Lennon, mastered by Abbey Road's
Simon Gibson, and cut to vinyl by
Alex Wharton, the box set is a deep dive into the production of Plastic Ono Band, with 11 hours of listening spread across eight discs, plus a hardcover book and poster to boot.
Hicks said in a statement:
"Yoko is very keen that in making The Ultimate Mixes Series, we achieve three things: remain faithful and respectful to the originals, ensure that the sound is generally sonically clearer overall, and increase the clarity of John’s vocals. 'It’s about John,' she says. And she is right. His voice brings the biggest emotional impact to the album."
