He first came to notice in 1958, when he was 14, in the Summer Exhibition at the Bladon Gallery, Hurstbourne Tarrant, while he was attending the nearby Andover Grammar School.
His main influences were at that time Jackson Pollock, Mondrian and comic books, with a special regard for those worked on by Stan Lee.
In 1968, Fields went to live in Earl's Court Square and shared a flat with Syd Barrett, who had just left Pink Floyd.
Fields continued to rent the flat and work in Barrett's former room, using it as his painting studio and remodelling the visual appearance of the property in his personal style.
[10] From 2013 to 2015, Fields worked for the preservation of Earls Court Exhibition Centre – designed in the 1930s by Howard Crane – and the surrounding area.
