Accompanying Lévy Gorvy's exhibition Calder/Kelly , this superbly produced catalog reveals the artists' friendship and their shared pursuit of abstraction. A timeline authored by Veronica Roberts traces the history of their relationship with previously unpublished letters between the artists and members of their shared circle of friends. In addition, Calder biographer Jed Perl examines resonances between the artists in his essay "Apollonian Affinities," and philosopher Robert Hopkins discusses the similarities and differences in their approaches to abstraction. Newly commissioned poetry by Dan Chiasson, Forrest Gander and Simon Perchik beautifully responds to works in the exhibition.
