Altoon Sultan blogs about the exhibition John Chamberlain: Choices at the Guggenheim Museum, New York, on view through May 13, 2012.

Sultan writes: "This 'right thing at the right moment', as John Chamberlain describes his process, must have been a great adventure for him. I could still feel the excitement and sense of discovery in his earlier work… The totality of each piece had a sweep and drama, but then there were all those marvelous details of color and surface, all perfect, and perfectly thrilling."
