I was listening to a lot of hip hop, music like Public Enemy that was about raising consciousness, and I realised I could feed that directly into my work, using images in a way that was a bit like sampling - taking images from diverse places, exploring the contradictions without trying to hide the seams.

When I was painting in art school - and I think many painters in the 1980s worked similarly - a finished painting would often be constructed from lots of other paintings underneath. Some of these individual layers of painting were better than others, but that was something that you would often only realise retrospectively.

It is a most extraordinary thing, but I never read a patent medicine advertisement without being impelled to the conclusion that I am suffering from the particular disease therein dealt with in its most virulent form.
