On a split bill at Triskelion Arts, Ms. Wasik and Ms. Zuerner explore transitions of different kinds. Ms. Zuerner's "Archaea," which will have its full-scale premiere this spring at a cemetery on the Brooklyn-Queens border, poses fundamental questions about life, death and the threshold between them. In "Granny Knot," Ms. Wasik is concerned with choreographic transitions, bringing what may seem peripheral or incidental to the center.
