Producer Harry Weinger used the original master tapes to create slightly longer mixes of a number of tracks, resulting in what is touted as "the best fidelity in any Supremes and/or Diana Ross collection ever," Billboard reported.
The project includes 11 Supremes No. 1s, four cuts from the period when the group was billed as Diana Ross and the Supremes, eight Ross solo tracks and a new remix of "You Keep Me Hangin' On" by the Almighty Associates.
The album kicks off with the August 1964 No. 1 hit "Where Did Our Love Go," and encompasses classics such as "Stop! In the Name of Love," "I Hear a Symphony" and Ross' "Theme From Mahogany (Do You Know Where You're Going To)," "Love Hangover," and "I'm Coming Out."
The package includes rare photos, a track-by-track recap and an essay by Brian Chin, who has contributed to two prior Supremes collections.
