Robert Williams is a Melbourne-based pianist who has collaborated with Ron Nagorcka since the early 1980s. His contribution to the development of this music during the 90s is considerable; encouraging a more disciplined approach with shorter, more fully notated pieces, and bringing professionalism to its performance. The interpretations of many pieces show his influence - such as Bunbundalui, Tarranyennah, Devils of the Night and in particular Noyenna (written by Williams on a Nagorcka theme) and Cockatoo where he wrote the piano part. Cockatoo is a unique achievement as it successfully juxtaposes an equal-tempered piano against one of Nagorcka's just intonation part.

After graduating from the University of Melbourne Conservatorium of Music and the Faculty of Education, Williams has worked in a wide range of musical activities earning him respect as a performer, composer and music educator. For many years he held the positions of Lecturer in Music and Music Therapy at Melbourne State College.

Williams has a long standing involvement with the performance and promotion of contemporary Australian music.His busy artistic life includes the co-ordination and direction of music festivals such as the Great Southern Sounds Festival held at the National Gallery of Victoria (1995 / 6), working as a music journalist and critic, and restoring and rebuilding pianos.
