A box set of seven-inch singles with nine unreleased David Bowie demos will arrive this spring.

The set titled Spying Through a Keyhole will be released via Parlophone Records to mark the 50th anniversary of the 1969 self-titled album, David Bowie.

The previously-unreleased demos were recorded during the era of Space Oddity, which David Bowie was renamed to. They were briefly released on streaming platforms last December, but this is the first time they will be released physically.
