This five-CD box includes almost every track from the studio albums Otis Redding recorded in his four year career with Stax. Since these albums included all the singles, the collection is effectively a "best of" plus more. My own vinyl collection was put together thirty years ago with some difficulty, scouring second hand record shops and paying the price of this whole box for anything resembling a decent disc. I envy lucky newcomers both for the price now required and the experience of listening for the first time to everything that is on offer.
Only one track (Hey Hey Baby) is missing from Otis's first album Pain in My Heart released in 1964. Thereafter every track is included from the four subsequent albums released before his death in December 1967: Otis Blue (his classic 1965 album and Europe breakthrough), Soul Ballads, Sings Soul and Dictionary of Soul. Also included are the best tracks from his joint album recorded with Carla Thomas (King and Queen) and all the tracks from two decent posthumous albums, Sitting in the Dock of the Bay and Love Man.
The only significant recordings missing are those from any of Otis's live albums, some of which are excellent. In this regard, I would particularly recommend Live in Europe and Live at Monterey (a scintillating album shared 50:50 with Jim Hendrix)
One thing to remember is that very few Soul stars of the day got to record albums in this quantity - you had to be right at the top of the tree to do so. Another is that the core personnel for the Stax backing band are the classic lineup of Booker T and the MGs, comprising Booker T Jones, Steve Cropper, Donald "Duck" Dunn and Al Jackson Jnr.
Overall, I recommend this collection to anyone who is interested in Soul or 1960s music. You, can of course, buy a smaller "best of" collection, but you will find many worthwhile lesser-known tracks in this one that you would otherwise be missing.
