It's been a productive spring for Pepper Fajans, the founder of this new space at Cadman Congregational Church in Fort Greene. With an ambitious volunteer team, Mr. Fajans, a dancer, choreographer and stage technician, has transformed the church's dilapidated gym into a light-filled arena for classes, performances and other gatherings, equipped with dance-friendly infrastructure like a sprung floor. An inaugural five-week series continues with performances by Hadar Ahuvia, Julian Barnett, Maiko Kikuchi and Mr. Fajans, before the space closes for more renovations this summer.
