Paul Trynka wrote a Bowie biography, titled David Bowie: Starman. It will combat all the David Bowie aggression you may have experienced as a result of the decisions he made in the 80’s.
Even if you’re one of those people who just “likes his early stuff,” this biography may help you revisit the pretty boy rocker who made it pop culturally relevant to not belong. This NY Times review has mostly good things to say about the biography as well as observant and cautionary notes about its size (“You may begin to circle its bulk warily”).
