Crossing The Line Festival

L'Alliance New York Gallery

This year's Crossing The Line festival highlights new collisions and experiments in audience and form, inviting art lovers to experience boundary-breaking visual art, music, film, dance, and theater all across New York City.

A family-friendly visual art exhibition-workshop—originally created by the husband-and-wife duo Clédat and Petitpierre for the Centre Pompidou—combines the tactile whimsy of mobile sculpture with interactive dance. In the evening, renowned cellist Sonia Wieder-Atherton presents the New York premiere of D'Est en musique, a gorgeous tapestry of film and music that she created in 2005 in collaboration with her late partner, the inimitable Belgian auteur Chantal Akerman.

Schedule of the Events:

Les tutomouves

As a lighter version of the monumental installation Les plantamouves originally created for the Centre Pompidou in Paris, this exhibition-workshop combines the tactile whimsy of mobile sculpture with interactive dance, inviting audiences of all ages to engage with more than 240 vibrantly colorful foam pieces through inventive video tutorials.

Marion Siéfert, Helena de Laurens

Le Grand Sommeil

New York Premiere

Back at L’Alliance New York after her acclaimed Crossing The Line 2022 debut, _jeanne_dark_, Marion Siéfert brings another ferocious performance to this year’s festival. Collaborating once again with actress Helena de Laurens, Siéfert crafts a wild investigation into the fantasies and norms of adolescence and womanhood, challenging de Laurens to embody the tortures, triumphs and terrors of teenage girlhood.

“With The Big Sleep, written and directed by Marion Siéfert, actress Helena de Laurens has won big. A golden score!” — Rosita Boisseau, Le Monde

In collaboration with the 14th edition of Seuls en Scène, Princeton French Theater Festival
