Conceptual artist Rashid Johnson (Born in Chicago IL, 1977) considers identity through material culture. Key signifiers recur in Johnson's work - such as black wax, branded wood, house plants, and shea butter - often juxtapozed with books and records that represent Black literary and musical traditions. At times, other, lesser-known symbols emerge, such as the Stigma Pi Phi's Boulé, the symbol of the first African American Green-letter organization. For Prospect.4, Johnson has created a multi directional microphone in the form of a cubed-shaped sculpture - the form reminiscent of a Sol Lewitt sculpture - with shelves for the artist's iconic objects, such as shea butter, books and plants. This new commission is designed to be activated by the visitor.
