The Stones banged this out, raiding the vaults to turn outtakes and rejects into gold.
Key Track: "Waiting on a Friend," with a sax solo by jazz legend Sonny Rollins.
Best Keith Moment: "Little T&A." Spoiler: She's his little rock & roll!
Low Concept: You haven't lived until you've seen Mick dance around in sweatpants in the "Hang Fire" video.
