Basquiat biography book

Well. I actually liked this book quite a bit. I should point out right away that you won't learn anything about Basquiat's work reading it, but I didn't truthfully expect to. That's not why I picked it up. The book is strictly about the artist's life and times, both of which were a hot mess. From everything recounted here, the eighties art market in New York sounds completely deranged (not that it's much different now, I suspect).
The portrait of Basquiat that emerges is not pretty, but judging from the number of sources, it's probably pretty accurate: impossibly childlike, uncontrollable, completely incapable of coping with the tasks of day-to-day life or of reining in his appetite for drugs, women, and alcohol. From the start of his career, he was a "functioning addict." By the end he was just an addict. The later parts of the book read like every episode of VH1's Behind the Music ever: "Unfortunately, the drugs, booze and out-of-control womanizing had begun to get in the way of the music" or in this case, the art. This is a painter who lived (and died) like Jim Morrison, Jimi Hendrix, or Janis Joplin.
For me, the most interesting parts of the Basquiat story are sociological. The book is full of tales of art dealers showing up at Basquiat's studio with duffel bags full of untraceable cash which they traded for paintings which were barely finished. They must have known, given how much coke and heroin Basquiat would leave lying around, where that cash was going. They just didn't care because they also knew how much money they stood to make off of the paintings. While he was still hot, of course.
As damning as the portrayal of art dealers is (and it's damning, especially when Hoban comes to Vrej Baghoomian, a bottom-feeder who swooped in to exploit what was left of the artist when Basquiat already had one foot in the grave), Basquiat himself doesn't exactly come out clean. He was ruthlessly exploited by a deeply cynical (a
