Mr. Sapoznik not only does an enviable job of painstakingly researching the history of Klezmer and its players, but brings his unique voice to telling the tale without placing himself above the remarkable story. This is not just a history of Jewish music, but the history of the American record industry and the birth of "popular" music as we know it today, recorded music in the hands of the average listener. Above all Mr. Sapoznik takes us on his own journey - influential names in Klezmer turn out to be members of his own family - and his expertise is a heritage well-lived. An absorbing subject and a wonderful book. Even if you know nothing about this music you owe it to yourself to read it.
