In my twenties I painted many black abstracts on 6 x 4 foot board. The large forms seemed to dominate an imagined landscape, giving me the feeling of Guardians. Guardians, protecting humans. In the 60s everything seemed so positive, they seemed unnecessary so I burnt the most of the work.
Looking through a number of the drawing I still have, I found the abstracts resonated with me and they evolved into sculptural heads.
We really do need Guardians to protect our habitat, as we seem to be doing very little about looking after the environment ourselves.
