The English translation of that book, Jazz: Its Evolution and Essence, was extremely important to me as a young man learning about the music. His detailed analysis of "Concerto for Cootie" is brilliant music criticism. His second book, Toward Jazz is almost as good, although in hindsight his critical approach in these first two books is somewhat severe. (How can anyone not like Johnny Dodds and Benny Carter?) His third book, The Worlds of Jazz, is something else. It's one of the strangest jazz books ever written: a set of allegorical fiction (for lack of a better term) which revolves around and illuminates the jazz world. My favorite piece is "Outside the Capsule," in which archeologist/priests of the future find a battered copy of the Bag's Groove album and painstakingly analyze the bass part of the title cut.
I think Hodier's music is amazing. I spun the Philips CD of Anna Livia Plurabelle, his strange James Joyce cantata, recently, and will certainly play some of his music today. RIP to a great composer and thinker.
I too read "Jazz: It's Evolution and Essence" when I was in high school and was awe-struck to see such intellectual firepower directed toward jazz. Despite its limitations it was a great book.
