In 1970 he took his first studio at SPACE, St. Katherine's dock, London, an artists' initiative set up by Bridget Riley and Peter Sedgley.
McKeever's early landscape photographic/drawing works such as Field Series (19780 and Waterfalls (1979) were influenced by the writings of Robert Smithson, followed by the over-painted landscape photographs in such groups as Lapland Paintings (1985–1986) and History of Rocks (1986–1988) where the painterly gesture comes to the fore.
McKeever has written numerous texts and essays on art, including personal reflections on painting and on other painters' works.
His 1982 manifesto titled Black and White...Or how to paint with a hammer (published by Matt's Gallery, London), expounded his internal conflict between the subjective nature of painting and the more conceptual parameters his work had adhered to so far.
Writings on other artists include Thoughts on Emil Nolde in 1996; Absolute Light, an essay on Russian icons for the British Museum magazine in 2004; and Thinking about Georgia O'Keeffe for the Louisiana Revy, Louisiana Museum of Modern Art, Humlebæk, Denmark.
