On what would have been John Lennon’s 78th birthday on Oct. 9, his album Imagine will receive an extensive box set treatment as John Lennon: Imagine: The Ultimate Collection hits stores.

Lennon’s widow, Yoko Ono, authorized the upcoming six-disc, 140-track collection and oversaw its production and creative direction.

John Lennon: Imagine: The Ultimate Collection contains four CDs and two Blu-ray discs; its biggest feature appears to be an extensive collection of mixes of the iconic album. There are “Ultimate Mixes,” which promise “whole new levels of sonic depth, definition and clarity to these timeless songs” (according to the set’s press release), as well as 5.1 surround sound mixes, raw studio mixes and, for the first time since the ‘70s, a four-speaker “Quadrasonic Album Mix,” which recreates the quadraphonic sound that was briefly in vogue in that decade.

The set also features a host of outtakes, rarities and isolated track elements (the separate pieces that were edited together into the produced version of the album’s songs).

The box also contains The Evolution Documentary, an “audio montage” that follows each song on the record from demo to finished product.

You can listen to a demo version of the title track below.

Additionally,  on Oct. 5, two films by Lennon and Ono, Imagine and Gimme Some Truth, will be released on DVD, Blu-ray, and digital platforms. Both films have been restored from original film reels, remastered and their soundtracks remixed. Both physical releases feature exclusive, previously unreleased extras including previously unheard “raw” studio mixes.

As previously reported, the Imagine film will also be re-released to theaters beginning on Sept. 17.

Yoko Ono is overseeing the publication of Imagine John Yoko, a book about the recording of Imagine, also to be released Oct. 9. Her new album, Warzone (which contains a cover of “Imagine”) will be released Oct. 19.
