The Kobayashi/Gray Duo made their international concert debut as winners of the prestigious United States Information Agency Artistic Ambassador auditions, touring South America and the West Indies. "The Duo's skill, energy and love they have for the music were all evident in this performance which brought the audience to its feet demanding an encore!" The Duo has presented lecture recitals at the First and Second International Conferences on Women's Work in Music in Bangor, Wales in 2017 and 2019; the 2002 International Workshops in Stavanger Norway; and conferences of the Music Teachers National Association, the American String Teachers Association, the College Music Society and the Society of Composers, Inc. They have toured throughout the Western and Eastern Cape Provinces of South Africa (2003), South America and the West Indies (1993) and the country of Thailand (2012). Notable US performance venues include the Dame Myra Hess Series and radio broadcast at the Chicago Cultural Center, the International Festival of Women Composers, the Music by Women Festival, the Hot Springs Music Festival and a number of museum series--the National Museum of Women in the Arts in Washington, D.C., the Joslyn Art Museum in Omaha, the Detroit Institute of Arts, and the Toledo Art Museum.
The Duo is in demand throughout the world for their skillful presentations of the standard repertoire as well as their specialty of the works of more than twenty-five 19th to 21st century women composers. The Duo has two CDs of works by women composers--Feminissimo! Women Playing Music by Women (2008) and Boldly Expressive! Music by Women (2000). Eight of these works are world premiere recordings, including Grande Sonate, Op. 8 by 19th century French composer Marie Grandval, which the Duo edited for Hildegard Publishing Company.
