In the first 15 minutes of the almost two-hour tour, after we had stopped at a mass grave of victims from the 1876 Brooklyn Theater fire, a shrill voice sounded, directing our attention to six bodies perched on a row of mausoleums, each lit from below. In seemingly random order, they began to fall backward and stand back up, to disappear and reappear, thanks to the simple but effective lighting.

Slater, engulfing Rachel Love’s operatic tones — made for the night’s most evocative spectacle.”
