I've been attempting to articulate how popular music and the "subcultures" associated with certain types of music are traditions. This is difficult since we are trained to think of these things in terms the new and inovative. Also we think of traditions as static, when in fact tradition is a dynamic phenomenon of transmission through time.
David Bowie I'm thinking is a great example of tradition in Rock music. In part Bowie as he's aged has become tradition for himself. But also he has always been transmitting popular culture and music to make his performances. Very little is original in Bowie. The Bowie exhibition at one moment points this out when showing his appearance on Saturday Night Live in the 1970's, by emblazoning a backdrop with this question "David Bowie Revolutionary or Plagerist?" The corect answer is neither the question misses a key aspect of Bowie as a performance artist: by returning to the use of make up as a Rock singer he abandoned the wuest for authenticity and originality.
