Ten years ago, the Italian choreographer Edmond Russo and the Israeli choreographer Shlomi Tuizer founded Affari Esteri ("foreign affairs" in Mr. Russo's native tongue). As part of both the La Mama Moves! Dance Festival and Danse: A French-American Festival of Performance and Ideas, the pair present "Embrace," a highly theoretical reflection on the malleable qualities of identity. Christina Clark, a poet, and the musician Oren Bloedow join them to make it a four-way conversation.
