interpretation. Gottlieb was a masterful colorist as well and in the Burst series his use of color is particularly crucial. He is considered one of the first color field painters and is one of the forerunners of Lyrical Abstraction. Gottlieb's career was marked by the evolution of space and universality. 1960s–1970s By 1960 Gottlieb's efforts on his "Burst" series, allowed him to greatly simplify his use of imagery. Gottlieb created “Burst” and “Imaginary Landscape” type paintings for the remainder of his career but, unlike some of his colleagues, he did not limit himself to one or two images.Discussion of Gottlieb's art is usually limited to mentions of “Bursts” or “Imaginary Landscapes”, which detracts from the broad range of ideas this artist examined. Gottlieb summarized his aims in a 1967 interview: But to me everything is nature, including any feelings that I have – or dreams. Everything is part of nature. Even painting has become part of nature. To clarify further: I don’t have an ideological approach or a doctrinaire approach to my work. I just paint from my personal feelings, and my reflexes and instincts. I have to trust these. A representative painting from this period is included in The Governor Nelson A. Rockefeller Empire State Plaza Art Collection in Albany, NY. In 1967 while Gottlieb was preparing for the Whitney and Guggenheim Museum exhibition he began to make small models for sculptures out of cut and painted cardboard that, he said, made him feel like “a young sculptor, just beginning”. These small sculptures evolved into larger works in cut, welded, and painted steel and aluminum. Gottlieb's foray into sculpture lasted only about a year and a half, but in that brief time he created a body of work that challenged the delineation between painting and sculpture. In ways similar to his friend the sculptor David Smith, Gottlieb's background as a painter made it impossible for him to visualize objects without color. Once he accepted this, Gottlieb was compelled to use all the tools he had developed in his long painting career – touch, visual balance, surface quality, and more – to make his sculptures, like his paintings, become "a vehicle for the expression of feeling… I feel a necessity for making the particular colors that I use, or the particular shapes, carry the burden of everything that I want to express, and all has to be concentrated within these
