Born on the dance floor in the 1970s amidst the shadow of post-Nixon America and a bruising recession, Disco offered an escape from American disillusionment and economic hardship. Disco celebrated inclusivity, hedonism, and liberation. When it became a commercial success, it became a cultural force that may have seemed vacant and superficial, but there was a deeper cultural significance. David Hamsley writes about that in his book To Disco, with Love: The Records That Defined an Era.
