Nora Musu is a Liberian artist whose art and life experience epitomize a multiculturalism that transcends boundaries or specific styles. She was born in the US to Liberian parents, grew up in Liberia, and has spent most of her adult years in the U.S. While a student at the University of Liberia, she studied under the renowned artist and art professor Cietta David Mensah. Nora Musu also holds a B.Sc. in Business Administration from Franklin University, Columbus, Ohio. Her work brings together an eclectic mix of visual boldness and an expressive, soulful sensitivity mirroring her life experience. Nora Musu drew on the broad panorama of her African ancestry to create her first US collection, Ngewo Domain, capturing impressions of ancient African stone and wooden sculpture. The artist achieves this effect with an innovative blend of acrylic polymers, and iron and copper particles enhanced by a process of rusting and patina that results in a three-dimensional sculptural relief effect. Ngewo Domain The artist believes that her talents, skills and knowledge come from "the Giver of All Things Good," Ngewo Domain, the mediator of nature in Mende legend and belief. The feminine Spirit of the Forest, Ngewo, who is the "Deliverer of All Things Good," appeals to her feminine side. Collectors Nora Musu's paintings are in several private collections, including the art collection of George Tanchevski of New Albany, Ohio; and the art collection of Abdul and Marie Sherif of Pickerington, Ohio.
