Maguy Marin, one of France's major choreographers, has a knack for taking us right up to the brink of cruelty. When she brought her startling—and at times bizarre—Umwelt to the Joyce in 2009, some audience members couldn't take it and walked out. Stoked by a pounding electronic score and accelerating rhythmic steps, in BiT the six dancers of Compagnie Maguy Marin work themselves into a frenzy. This new work may go beyond the brink, judging from the warning that has been issued: "This performance contains depictions of sexual violence." Proceed at your own risk. Oct. 25–29. joyce.org.
