Great book detailing how jazz transformed from the swing era to bop. The book is all interviews conducted by Ira where he speaks to many jazz legends describing their experiences during this time, Ira does a great job weaving parts of the interviews together into a steady progression of people who played with the same bands, in practically chronological order. This book also doesn't hold back the hardships players faced during this time, jim crow, racism, and how drug use plagued the jazz world are all topics covered. It was also fascinating to learn more about some of these swing bands and the stories behind them. It's one thing to read what happened in a textbook, it's another kind of connection to read interviews of people who were there and learning about what was (and wasn't) included in textbooks. Only negative of the book is that the text looks kinda old-timey or not blurry but kind of less clear if that makes sense, but it didn't detract anything from the books contents. Great read!
