‘Theater of Public Secrets’ premiering at The Roberts Theater, in its complete two acts is a bona fide Koresh Dance classic already. Shown in excerpts in Philly last winter, choreographer Roni Koresh has been developing and expanding it all year, and it has become the Koresh work to see on tour in Japan, Turkey and Israel. For those not in the mood for holiday fluff, this is dance drama you can sink your teeth into. Melissa Rector and Jae Hoon Lin’s incredible chemistry depicting a passionate and troubled affair, is hypnotic.
