Unconcerned But Not Indifferent is a beautifully produced monograph that draws exclusively on the archives of the Man Ray Trust, one of the largest Man Ray archives in the world, and one which has remained largely unexcavated since it was brought to the U.S. in the late 1990s. The book is structured chronologically across the four phases of Man Ray's working life, in New York, Paris, Los Angeles and Paris again. Works reproduced here range from typographic studies done in 1908, through paintings, objects and sculptures to Man Ray's pioneering photography, from the Rayographs (abstract photographs produced from found objects) and Solarizations (a procedure of tonal reversion developed by Man Ray and Lee Miller), to his fantastic portraits of Andre Derain,Pablo Picasso, Jean Cocteau, and many others.
