Brett blossomed into abstraction as a 13 year old in Mexico and kept that eye for the next six decades. Any similarity to Kline, Motherwell or anyone else is a coincidence. Brett was not only a photographer, he was also a magnificent sculptor. And the vast majority of his sculptures are three dimensional presentations of his abstract photography. It all goes together because that is how Brett saw the world.
That's a good point, one that I hadn't thought of, I knew he sculptured and worked with wood but I hadn't connected the two together.
