Also, the notion that we each tend toward certain creative roles, using the example of Keith Richards creating opening riffs, then handing off the melody, speaks to the sometimes highly-compartmentalized nature of the process and maybe even the existence of certain innate creative preferences. Very cool interview.
Robinson's book is a great read, too.
