Cheap, disposable, often with poor audio quality but with great visuals, flexi discs were vinyl's poorer cousin in the pre-digital age. Given away with magazines or sent out by advertisers, they were a splashy way of getting your message heard. Pressed onto laminated card or thin, wobbly plastic, these discs extolled the virtues of washing powders, beers, and banks. This book brings together over 150 of the most remarkable British flexi discs from the 1950s to the early 1990s, chronicling the varied and sometimes bizarre uses of these flimsy records, and the result is a fascinating archive of post-war design and advertising ingenuity. Wobbly Sounds is part of the Four Corners Irregulars, a series about modern British visual culture.
