Tin Pan Alley [PDF ebook] 

In Tin Pan Alley we see the beginnings of the pop world as we now know it: commercial, constantly capturing, exploiting or even occasionally creating a public mood. The Alleymen were workers as much as artists. This book, first published in 1982, explores how the change occurred, the ways in which songwriters organised themselves to get greater control over their products, the social circumstances that influenced their choice of subject-matter, the new forms, such as the integrated musical, developed for maximum appeal, the vast publicity structure built to market the merchandise, and, of course, the many stars who came to fame by taking a walk down the Alley.
