Sufragatte City
Five Years
Scary Monsters
Ziggy Stardust
Space Oddity
and so many more... Bowie is the greatest, he's always been so far ahead (maybe except in the 80s where he gave up to the bling ;))
Btw, I hope everyone has watched the movie Velvet Goldmine, if not, rush to netflix and get it (it could be quite hard to find at a blockbuster). Ewan McGregor playing Iggy Pop rocks!
