Doug Frohman is an artist whose studio is upstairs from mine at the Cornelia Arts Building in Chicago. He makes abstract paintings on canvas and panel, usually at least 48" x 48" upwards in size, which are an absorbing combination of all the ways a painter can make a mark on a surface. He takes paint and he brushes it, lightly and roughly, thickly and thinly, he scrapes the paint off and relays it, he uses a knife and a rag. When he's covered the whole surface, he goes at it again, and again, putting down one small area next to or over another small area until the whole picture finally emerges from this accumulation of stuff. The overall tonality and visual effect of his paintings is like Sean Scully, the difference being that Scully's "blocks" are often larger.
After Doug spoke about his paintings for a while, he said something that might be a profound way of describing this process. Or it might not be. But it probably is.
"When the picture changes ... it changes."
