Yeah, that is a hard book to read, but a good one in its way.
Here's another of my favorites. Louis Armstrong, His music changed many sectors of the musical world and always strengthens me.
Interesting parallels for me with Louis. His father and my father are both named William Armstrong. He said/thought his birthday was July 4, but turns out it was August 4. My parents' first child was stillborn on July 4, and was going to have my name, and I was born 13 months later on August 4.
The man was a genius of many talents. Few know how much he wrote, he was a compulsive and excellent writer, and he created interesting artwork as well.
