In 1963 Louisiana, a 39-year-old divorced black woman toils away in her own personal hell.

The woman is the titular hero of Tony Kushner’s musical, “Caroline or Change.” Her purgatory, the basement of 913 St. Anthony St., and her toil — a daily torrent of dirty laundry, indignation and unfulfilled dreams, courtesy of Caroline’s employers, the Gellman family.
