Ci sono ampie tracce dei lavori liquidi di Mark Boyle, Joan Hills, Mike Leonard e Peter Wynne Willson per i concerti di Soft Machine e Pink Floyd dell'epoca psichedelica all'Ufo Club di Londra nel libro di Kevin Foakes Wheels of Light (Four Corner Books, 2022), che segue l'evoluzione tecnologica e artistica dei light show britannici da metà-fine anni Sessanta ai decenni successivi - in ambito musicale, ma non solo - dando rilievo a quei primi esperimenti pionieristici e innovativi di grande impatto e fortissima esperienza sensoriale (non soltanto visiva).
The author’s research, triggered by a modern- day DJ’s encounter with a Solar 250 projector and Luton-based Optikinetics, has resulted in a book which is nothing less than a jewel of entertainment lighting history. Always engaging, and with an obviously warm regard for his subject, Foakes takes the reader back to the early days of effect lighting; to bubbling oils, to Aldis projectors and the extraordinary, hand-painted effect wheels that would today grace the walls of any art collection. Although it predominantly focuses on the artworks themselves, the book also provides a fascinating overview of those who drove this cultural phenomenon. Those early days of effects projection, from the early 1960s and through the 70s and 80s, have been a source of fascination and inspiration for light artists and lighting designers ever since. From strobing, monochrome op-art at the Fillmore, to The Soft Machine and The Pink Floyd bathed in swirling, coloured liquid projections at the UFO Club, they were innovations that have cast many long and wonderful shadows, through disco, punk, rave and beyond.
