The Alchemist’s Veil, created, choreographed, and performed by dance artist Maureen Fleming, is a fascinating fusion of surreal movement poetry and spellbinding visuals, inspired by the paintings of renowned artist Georgia O’Keeffe. Part dance, part dream, part art appreciation, it’s altogether a showcase for Fleming, who is celebrating her 70th birthday this year and the 35th anniversary of her 1989 debut with La MaMa.
