The Lydian Chromatic Concept of Tonal Organization: The Art and Science of Tonal Gravity

Composer, theoretician, band leader, George Russell, first published the  Lydian Chromatic Concept in 1953, and, for almost 50 years, worked on  further refining it. This result is this final edition, published by the  estate of Mr. Russell. "Surpasses any musical knowledge I've been  exposed to." Ornette Coleman. "All of the music's most important  developments from modal improvisation to electronics...to free form  atonality to jazz-rock have taken cues from Mr. Russell's pioneering  work." Robert Palmer, The New York Times.
