Music historian James Wierzbicki sheds light on how the Fifties' pervasive moods affected its sounds. Moving across genres established--pop, country, opera--and transfigured--experimental, rock, jazz--Wierzbicki delves into the social dynamics that caused forms to emerge or recede, thrive or fade away. Red scares and white flight, sexual politics and racial tensions, technological progress and demographic upheaval--the influence of each rooted the music of this volatile period to its specific place and time. Yet Wierzbicki also reveals the host of underlying connections linking that most apprehensive of times to our own uneasy present.
