David Bowie died of cancer on 10th of January in the age of 69. Like the rest of the world I feel sorry for him. He was a brilliant musician, truly one of the greatest songwriters for all time. He was odd, creative, impressive and passionate for music. Many say that without this man there was no pop-music and it's hard not to agree. 
He changed his image for many time. In 70's he was a Ziggy Sturdust: an alien from space. Also he was a Thin White Duke wearing a formal suit. In 80's he tried himself as an actor and he became the Goblin King with funny hair and weird make-up. And as I remember he had heterochromia (when your eyes have a different eye color). 
Rest in peace, David. Thank you for your music and inspiration. You will be remembered. Goodbye, Ziggy Sturdust.
