A David Bowie rarities box set is due out in the spring.
Spying Through a Keyhole will feature nine demos recorded around the time Bowie started working on "Space Oddity" -- all pressed on seven-inch singles. Most of the tracks feature just Bowie on vocals and guitar. The demos were briefly available on streaming services late last year to renew the copyrights, which were set to expire in 2018.
In other Bowie news on what would have been his 72nd birthday, the David Bowie Is app, narrated by Gary Oldman, is now available through the Apple Store and Google Play.
