쳇 BakerJean Baker is a trumpet runner and vocalist loved by the public for his soft lyrical performance, sweet voice that stimulates motherhood and handsome looks. Known as "My Funny Valentine," he was called the Prince of "Cool Jazz", who began his diary around the West Coast in the 1950s. Jean Bakers music impressed people, but he lived a life of loneliness and wandering because he never escaped from drug addiction. Nevertheless, why is his music still valid? The author digs into a life of contradictions and a world of art through an extensive interview with Jean Bakers surroundings and an extensive survey of unpublished material. This biography is regarded as cruel and frank, but a perfect masterpiece. * This book is a revised version of Deep in a the long night of Chet Baker, published in Eulyu History in 2007. b
