On September 11, 2001, the sculptor Michael Richards was working in his studio on the 92nd floor of the World Trade Center, Tower One. He was 38, and he died that day. Yet Richards remains an indelible pillar of contemporary Black art. In the years from 1990 to 2001, he explored historical and modern racial injustice, fusing mythological and religious allusions with pop culture references and a now heartbreaking fascination with aviation. Pieces like Swing Lo, a wooden chariot outfitted with neon party lights and blasting Jamaican reggae music, remain as relevant as ever. The first museum retrospective on the artist, which opened at Miami’s Museum of Contemporary Art and is now at the Bronx Museum of the Arts, honors his nuanced body of work and includes archival interviews and photographs. —Lucy Horowitz
