Though based in Los Angeles, the mid-century Light and Space movement is well represented in New York galleries, a happy circumstance aided by Pace Gallery’s long-term relationships with key artists. ‘Irwin/Bell: The ‘60s’ at Pace’s Tribeca offshoot, ‘125 Newbury,’ presents work by Larry Bell and Robert Irwin that revisits their early shows in New York, including the premier of Irwin’s aluminum disc paintings in 1968. Installed in a back gallery with a bench inviting visitors to sit and contemplate, this untitled piece from 1967 presents a circular aluminum form that exists materially but appears to be composed entirely of light and shadow. (On view in Tribeca through Jan 11th).
