Is the current revised edition dramatically different from the previous editions?
Yes. Generally speaking, the previous editions of the Lydian Chromatic Concept of Tonal Organization (dating back to 1953) were focused more on the how-to aspect of improvising. The more robust, comprehensive and detailed current volume adds never before published depth and dimension through exhaustive examples of analysis, scales, background information and test examples for the student. Volume Two, the completion of the entire work, is currently in development.
