In 1945–46, Russell was again hospitalized for tuberculosis for 16 months. Forced to turn down work as Charlie Parker's drummer, during that time he worked out the basic tenets of what was to become his Lydian Chromatic Concept of Tonal Organization, a theory encompassing all of equal-tempered music which has been influential well beyond the boundaries of jazz. The first edition of his book was published by Russell in 1953, while he worked as a salesclerk at Macy's. At that time, Russell's ideas were a crucial step into the modal music of John Coltrane and Miles Davis on his classic recording, "Kind of Blue", and served as a beacon for other modernists such as Eric Dolphy and Art Farmer.
