Like the world would really need another book on Miles Davis, Richard Cook, editor of Jazz Review, cleverly stirred his It’s About That Time: Miles Davis On and Off Record away from being another hagiography. Begin with Birth of the Cool and end with posthumous Doo Bop, Cook’s ingenious assessment of Miles’s music and life is based on his albums. What makes this book rewarding is Cook’s meticulous evaluation of the recordings. It takes me longer to read because I have to pause and listen to the albums (only the ones that I own) to appreciate the level of details and the liveliness in his writing. Without being too technical, Cook’s vivid language will help readers understand the aesthetic qualities and beauties of Miles’s works of art.
