This Mix accompanies “Crystals, Angels and Raindrops,” Chapter 10 of All Hopped Up and Ready To Go: Music from the Streets of New York 1927-77. Specifically, it covers the "girl group" sound of the early-mid 1960s, from the Shirelles to the Shangri-Las, via Phil Spector's Wall of Sound and the vibrant scenes to be found at the Music and Brill Buildings of Broadway.
