This book focuses on American opera singers and what their recordings say about their artistry. It is not a book about all American opera singers, since many who had important careers on stage, made few, if any, recordings. And many of those who did make recordings, did so prior to the introduction of electrical recording in 1925 (and the resulting advances in the reproduction of the human voice). Opera enthusiasts can only imagine the sound of Farinelli's voice or read what his contemporaries have written about it, but with almost any famous or near-famous singer of recent years, enthusiasts do not have to imagine. Their voices are available through the technology of sound recording. There are 53 entries, one each for 52 singers and a composite entry for a group of Hollywood vocalists. Each entry contains biographical information and is followed by a discography of operatic recordings to be used in conjunction with the critical commentaries. The entries are in alphabetical order by the singer's last name and provide critical analyses of key recordings and of the artists' gifts and limitations.
