An Aboriginal Australian and Native American documentary narrated by award-winning actor Jack Thompson, One Heart-One Spirit tells the story of Kenneth Little Hawk, an elder Micmac/Mohawk performing artist, meeting the oldest surviving culture on the planet: the 40,000 year old Yolngu nation located in northern Australia.

Every 'overnight sensation' in the music industry is preceded by a few years of fine-tuning the act. But 40,000 years? From the far north of Australia, YOTHU YINDI draws on the song cycle of its Arnhem Land ancestors to create a mesmeric mix of traditional Aboriginal music and rock 'n' roll. Into the Mainstream takes us on a journey across the vast continent of America with YOTHU YINDI, on the 'Diesel and Dust to Big Mountain' concert tour featuring MIDNIGHT OIL and American Indian band GRAFITTI MAN. The bands travel 16,000 km over 38 days and play to crowds of up to 10,000. On the way they meet American Indian communities to talk about land rights and cultural identity, culminating in the presentation of a gift from the Yolngu people in Arnhem Land to the Navajo elders in Big Mountain, Arizona. YOTHU YINDI proves to be a revelation on tour - Aboriginal traditional music and dance quickly become the latest American vogue in performing art.
