Lori Belilove & The Isadora Duncan Dance Company return to the exquisite Walled Garden Amphitheater at Untermyer Gardens in Yonkers in a program entitled "a glow over this sad earth."   Belilove has selected dances by Isadora Duncan and her own original works that offer moments of hope and beauty as well as expressions of lament and tragedy.  The Company will perform in the same site that hosted a 1923 performance of The Isadorables, the troupe formed by Irma Duncan.
