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. In addition, they have toured South Africa and Thailand and have presented at the International Workshops in Stavanger, Norway, and the First International Conference on Women's Work in Music in Bangor, Wales. 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 Hot Springs Music Festival, 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—and conferences of the Music Teachers National Association, the American String Teachers Association, the College Music Society and the Society of Composers, Inc.
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.
