From Edison to Marconi - The First Thirty Years of Recorded Music (Hardcover): David J. Steffen From Edison to Marconi - The First Thirty Years of Recorded Music (Hardcover)
David J. Steffen
R916 R682 Discovery Miles 6 820 Save R234 (26%) Ships in 10 - 15 working days

As with any profound technological breakthrough, the advent of sound recording ushered in a period of explosive and imaginative experimentation, growth and competition. Between the commercial debut of Edison's ""talking machine"" in 1889 and the first commercial radio broadcast three decades later, the recording industry was uncharted territory both in terms of technology and content. Wire, cylinder and disks competed to become the dominant recording technology, and for early industry pioneers, the primary concern wasn't what they recorded, but that they had a recording to sell. The industry headed in myriad directions - led by luminaries like Edison and Marconi, plus a host of long-forgotten others - until affordable phonographs and commerical radio gave it direction, creating public demand for certain recordings. By the time the dust settled, companies, practices and genres that even now profoundly affect the recording industry were firmly entrenched. This history of the earliest years of sound recording - the time between the phonograph's appearance and the licensing of commercial radio - examines a newly created technology and industry in search of itself. It follows the story from the earliest efforts to capture sound, to the fight among wire, cylinder and disk recordings for primacy in the market, to the growth and development of musical genres, record companies and business practices that remain current even today. The work chronicles the people, events and developments that turned a novel, expensive idea into a highly marketable commodity. Two appendices provide extensive lists of popular genre and ethnic recordings made between 1889 and 1919, and a bibliography and index accompany the text.

Edison - Inventing the Century (Paperback, Revised edition): Neil Baldwin Edison - Inventing the Century (Paperback, Revised edition)
Neil Baldwin
R1,041 Discovery Miles 10 410 Ships in 10 - 15 working days

The genius of America's most prolific inventor, Thomas Edison, is widely acknowledged, and Edison himself has become an almost mythic figure. But how much do we really know about the man who considered deriving rubber from a goldenrod plant as opposed to the genius who gave us electric light? Neil Baldwin gives us a complex portrait of the inventor himself--both myth and man--and a multifaceted account of the intellectual climate of the country he worked in and irrevocably changed.
