I have completed this manuscript Just Remember This, or as American Pop Singers 1900-1950+, about music before the 1950s in America. It perhaps offers knowledge and insights not previously found in other musical reference books. I have moreover been working on this book very meticulously over the past twelve-plus years. It started as a bit of fun and gradually became serious as I began to listen along with the vocalists of popular music, of the era before 1950, essentially just before the dawn of rock and roll. If you can call it that! Indeed genre and labeling of American music started here, and then from everywhere. While the old adage of always starting from somewhere could be noted in every century, the 1900s had produced the technology. Understanding the necessity, more so, finds a curiosity on the part of a general public hungry for entertainment, despite 6 day work weeks, World War I, the Great Depression, and World War II.
