It is a collection of 74 tracks distributed in six CDs, around a quarter of which were unreleased prior to the album; all the tracks were subject to extensive re-mastering at EMI's Abbey Road Studios. The set starts with a selection of early tracks by the members of the band before they joined Deep Purple.
The box set also houses a format book written by Deep Purple archivist Simon Robinson, which tells the band's story via 120 pages of text, pictures, cuttings, memorabilia, musician profiles and discographies.
