Kahn is a Coltrane expert and fills this book with lots of insider facts and interviews about Impulse Records. Coltrane was a visionary musician, and he was given free reign at Impulse. Here’s a quote from Yusef Lateef:

[p116] “I was free to record what I chose to: that was a strong point to me. When you give a person, freedom they give you their utmost. I think Bob Thiele realized that.”
