Change, and the apparent necessity and at least the endless capacity for it, subtends the entire process that was David Bowie. 

Bowie scoffed in interviews that he was a “chameleon”, involved deeply and publicly in a continual process of “self-reinvention.”  In that case, one has to wonder what to make of Bowie’s apparent dismissal of Ziggy Stardust and other personas as merely participants in so many stories about whom there is nothing we need to understand.  Bowie confessed that he put on guises, collected voices and then acted them out. And also that he took from Buddhism the transience of it all. So the so-called chameleon of rock, spiritually impressed by the transience of existence, disdains the transience of his own flow of characters and characterizations.
