Drawing on decades of work observing and researching the Mormon Tabernacle Choir, Michael Hicks examines the personalities, decisions, and controversies that shaped America's choir. Here is the miraculous story behind the Tabernacle's world-famous acoustics, the anti-Mormonism that greeted early tours, the clashes with Church leaders over repertoire and presentation, the radio-driven boom in popularity, the competing visions of rival conductors, and the Choir's aspiration to be accepted within classical music even as Mormons sought acceptance within American culture at large. Everything from Billboard hits to TV appearances to White House performances paved the way for Mormonism's crossover triumph. Yet, as Hicks shows, such success raised fundamental concerns regarding the Choir's mission, functions, and image.
