The PBS animated series “Blank on Blank” has devoted their latest episode to a 1998 interview with David Bowie. In just over 5 minutes Bowie and music executive Joe Smith manage to cover a lot of ground including the rock and roll life style, the problems with fame (or the lack thereof), the origins of Ziggy Stardust and the pitfalls of spending too much time looking backward or trying to cling too tightly to something.
