Gai arrived in Sydney after graduating from the University of Adelaide where she studied Jazz Performance. She has worked with Carl Orr, Mark Simmonds, Paul McNamara, Sandy Evans, Jackie Orzaczky, Jann Rutherford, Lloyd Swanton, Janet Seidel, Don Burrows and Roger Frampton and others.

In 1996/7 she studied with soprano saxophonist and composer, Jane Ira Bloom in New York. Upon her return to Sydney she formed the Gai Bryant Quartet. From 1997-2000 the Quartet toured throughout Australia, Korea, Hong Kong and Taiwan performing concerts and conducting workshops. In October and November 1999 the Quartet completed a series of live performances with poets in Hyde Park as part of a vision to access Sydney’s open spaces for small acoustic and cross-art form performances.

“Gai is a particularly fine & subtle arranger. Her original music oft has a simultaneously ‘spare’, yet ‘richly orchestral’ quality.”

Early 2000 Gai studied Taegum at the National Korean Performing Arts Centre in Seoul with WON Hyang-Juan, master of traditional Korean music. In September the Quartet toured Korea with WON Hyang-Juan and his family performing compositions by Gai and Won Hyang-Juan for a combined ensemble at the Korean Performing Arts Centre, Seoul.
