Si is one of the world’s leading contemporary players of Australia’s iconic instrument, the didgeridoo. Behind the powerful momentum of his playing is a hidden and rich life. Si has played concerts and travelled through out the world and also back home in Australia, deep into the outback regions. Si’s principal exploration has been how to use the breath and the vibration of the didgeridoo, to invigorate his life and the lives of others. He has developed a unique breathing method that is now called Didgeridoo Pranayama.
