Today a new exhibit called "John Chamberlain: Choices" opens at the Guggenheim Museum. The retrospective exhibition features the work of postwar sculptor, John Chamberlain, who utilized shiny car parts, aluminum foil, foam and even paper that looks like crunched metal to create three dimensional abstraction. Chamberlain, who died in December, saw “fit” and “choice” as the guiding principles of his work. The museum is displaying 97 works, which generally fall into Abstract Expressionism, Minimalism and Pop categories. “John Chamberlain: Choices” is arranged chronologically up the museum’s ramp, except for one work on the main floor of the rotunda and one outside the museum on Fifth Avenue. “SPHINXGRINTWO,” a 16-foot tall twisted aluminum double arc sits on the ground floor of the museum, making its public U.S. debut. Outdoors, the 20-foot tall “C’ESTZESTY” is made of chromium-plated steel and stainless steel. The exhibit runs through May 13, 2012.
