Michael Sadler works in series developing a theme by focusing on a single word or short phrase. The work he has produced in the last few years has been based on his layman's interest in astronomical phenomena and space exploration. His work began with his 'Transit' series paintings and developed to his most recent 'Constellation' paintings. Sadler has become increasingly focused on using fewer formal and compositional elements in order to produce a group of closely related images which convey the sense of a credible abstract world.
His work is held in both public and private collections.
