The work of the Israeli choreographer Ohad Naharin, one of today's great dance makers, is eerie and unsettling and often achingly beautiful. But he doesn't get enough credit for being funny, too. In "Decadance," performed by the junior wing of his Batsheva Dance Company (don't lower expectations: they're spectacular), Mr. Naharin stitches a quilt of excerpts from two decades of work. It captures his light and dark sides, as well as his humor.
