More than 300 artists, dancers, community leaders and Harlem neighbors gathered at MIST Harlem, 46 West 116th St., on Monday, Aug. 29, to celebrate “harlem is . . . Dance,” an art exhibition and performance evening created by Community Works NYC to highlight the importance of dance and movement in maintaining Harlem as a cultural capital. The program saluted contributions over the years from Marie Brooks, Ruth Williams and Dele Husbands in creating schools of dance and companies that brought dance traditions to young people and performed across the city and beyond.
