After doing the imaginary landscapes until say 1956, in '57 I came out with the first Burst painting... There was a different type of space than I had ever used and it was a further clarification of what I was trying to do. The thing that was interesting that it was a return to a focal point, but it was a focal point with the kind of space that existed in traditional painting. Because this was like a solitary image or two images that were just floating in the canvas space. They had to hold the space and they also had to create all the movement – that took place within the rectangle.
