Conversation Piece [Box Set]

Strictly speaking, there aren't many unheard tracks here. Everything from the Spying Through a Keyhole, Clareville Grove Demos, and The "Mercury" Demos sets are here, along with a brand-new mix of the Space Oddity album by Tony Visconti, one that restores "Conversation Piece" as part of its sequence. Setting aside the new mix of Space Oddity, that leaves 11 tracks out of 75 that are making their debut here, including several that have never been bootlegged and a couple that weren't even known to exist.
