The Creators Project posted a piece on collaborations between artists and celebrities. They mentioned collaboration on Shadows and said the following:
In this project, Reeves is not only the model, but also the conceptual touchstone and contributing writer, co-creating with Grant a meditation on what shadows are as “phenomena, image, and metaphors.” Blending her instinct for what makes a good picture with his facility in using his body as an instrument of self-expression, and later marrying her capacity for visual narrative and his language-based way of searching for meaning, the perhaps unlikely duo have produced an utterly poetic, strange, and emotional work of art that took them both in unexpected directions. Whoa.
