Saturday Night Forever

If all disco means to you is records like 'I Will Survive' and 'YMCA', tacky fashions and glitter eyeshadow, this book will be a real revelation. For Alan Jones and Jussi Kantonen, disco was an essential soundtrack to their lives. They loved its total hedonistic excess, its drive, its punch and its sweet, catchy melodies. For every chart hit that pounded into the public's consciousness, countless other better tracks were causing hair-raising highs on dance floors where Alan and Jussi and thousands of aficionados like them were strutting their funky stuff.

Disco started in obscure underground clubs as a glamour-filled reaction to the plodding, self-indulgent rock music of the late '60s and really took off in the excitement-parched early '70s. Created by people marginalised by their colour (black), race (Latino), sexuality (gay) or class (working), the music and its attendant lifestyle inevitably became watered down and distorted once it slipped from the control of small independent labels and became a worldwide craze. The massive popularity of films such as Saturday Night Fever and the accompanying Bee Gees soundtrack led people to believe that this was disco. But the authors, by exploring such diverse strands as Eurodisco and roller disco, gay disco, and disco fashions, drugs and clubs, show this to be untrue, and instead uncover the magical, multi-layered genre in all its shining, strobe-lit glory. They believe in mirror balls.
