Unlike his contemporaries Jackson Pollock and Mark Rothko, de Kooning’s paintings refer to natural forms and specific places or events, pushed into pure abstraction by his reliance on color and the deep build-up of paint to create form. Depth and perspective are subordinated to the flattening effects of his slashing, violent brushwork. Some of the "abstract landscapes" from 1957 to 1963 are based on the landscape around Long Island Sound, including Merritt Parkway, a local highway. Speed is suggested by the controlled thrusts of the brush while the naturalistic palette conveys the crisscross of the road through the landscape.
