As part of the celebrations marking 50 years since David Bowie's first hit, 'Space Oddity' in 1969, and following the 'Spying Through a Keyhole' and 'Clareville Grove Demos' collections, 'The 'Mercury' Demos' are 10 early Bowie recordings captured live in one take to a Revox reel to reel tape machine in David's flat in spring 1969, with accompaniment from John 'Hutch' Hutchinson on guitar and vocals. The version of 'Space Oddity' from the demos, originally released with edits on the 'Sound & Vision' boxset, is presented here in its true context for the first time. The other nine recordings on the album are all previously unreleased.
