Peter Shapiro, Turn the Beat Around, the Secret History of Disco:

But disco wasn’t simply an escape from the language that had divided America, it was at the same time an embodiment of the very tensions and schisms that the rhetoric sought to express and resolve. Disco was at once about community and individual pleasure, sensation and alienation, orgy and sacrifice; it promised liberation and constraint, release and restraint, frivolity and doom. Disco was both utopia and hell.
