The glam-rock singer, who shot to fame in the late Sixties with Space Oddity, has released the recording Where Are We Now? on iTunes to coincide with his 66th birthday.
A follow-up album called The Next Day is set to be released in March. Bowie has not performed live since 2006 and has rarely been seen in public since then, leading to rumours of possible ill-health which were denied by his spokesman.
Where Are We Now? was written by Bowie, and was recorded in New York, where he was last reported to be living with his wife and daughter. It's
accompanied by a video.
