Winner of the 1993 Primrose Competition, Ms. Ngwenyama came to national attention when she won the Young Concert Artist International Auditions - the first violist chosen in 14 years - at age 17. Plaudits followed her debut recitals in Washington, D. C. at the Kennedy Center and in New York at the 92nd Street Y, and in 1997 she received an Avery Fisher Career Grant.

Ms. Ngwenyama has performed throughout the United States, including appearances with the Atlanta, Baltimore, Buffalo, Columbus, Indianapolis, and National Symphony orchestras. A popular recitalist, she has been heard at Tokyo's Suntory Hall, the Louvre, the Ford Center in Toronto, Seattle's Meany Hall, Spivey Hall, and the Maison de Radio France. A recent participant with the Chamber Music Society of Lincoln Center: Chamber Music 2, she is also a regular performer at such festivals as Spoleto USA and Vancouver. She has also appeared with the festivals of La Jolla, Vail, and Marlboro as well as the Italian Bolzano and Este Festivals and the Festival de Radio France et Montpellier.

Ms. Ngwenyama is no stranger to television and radio appearances. Her performances at the White House, commemorating the 10th anniversary of NPR's Performance Today, also featured artists Wynton Marsalis, James Galway, Denyce Graves, and Murray Perahia. Prior to that, a vivid portrait of Ms. Ngwenyama was televised nationally on CBS Sunday Morning with cultural correspondent Eugenia Zukerman. Ms. Ngwenyama was also featured on the Emmy-nominated PBS program 'Sound of Strings' in the Musical Encounter series.
