Voices for organ & Didgeridoo was commissioned by the City of Melbourne to relaunch the Melbourne Town Organ in 2001.

The piece was the first collaboration between Glass and didgeridoo player Mark Atkins.

The two would later work together on Orion.

This world premiere recording of the piece is performed and produced by Michael Riesman， organist and music director of the Philip Glass Ensemble.

Initially Voices began as an idea for combining the music of two established musical traditions - the organ representing the European church and art music and thedidgeridoo representing the indigenous music of Australia.
