Myles Boothroyd of Central Michigan University wrote a thesis a few years back called "Modal Jazz and Miles Davis: George Russell's Influence and the Melodic Inspiration Behind Modal Jazz".
19 pages written by an academic of music might be hard to digest, but for you music and jazz lovers there is some great history here about how modal jazz was conceptualized, the many technical aspects of modal jazz and discussions on Miles Davis' approach and the "Kind of Blue" recording.
Knowledge is never boring!
