Lewis Porter is known as "THE" guy when it comes to Trane. Incredibly knowledgeable, transcribed all his solos, etc. One of the top jazz scholars around. This is a no brainer book for any fan of Trane.
I also recommend Ashley Kahn's A Love Supreme: The Story of John Coltrane's Signature Album. As a book about 1 record, it might be a bit overkill per some, but for a treasured masterpiece like ALS, is there really such a thing?
