There was an Indigenous music congress held in Sydney recently. One of the topics discussed was the use of didgeridu as a means of evoking "authentic" indigenous Australian sounds.

There is a big push by indigenous musicians/organisations to make people aware that it is a traditional instrument which is tied up with considerable cultural significance. Didge playing is part of a particular cultural practice, and is not separate from specific rituals etc. besides this, didge is not played in all parts of Australia. It is quite inappropriate for East coasters to play it, for instance. It is also not acceptable for women to play it.

How do you reconcile these issues - to respect the significance of the instrument and the culture it is tied to - with the musical freedom to explore different traditions?
