Hailing from far north Queensland, 16 Indigenous girls and young women are taking the stories of Western Australia's Pilbara region to the United Kingdom.
The Marliya choir will be joined by members of Australia's national children's choir, Gondwana Voices, as well as the UK's Farnham Youth Choir and Royal Scottish National Orchestra Youth Chorus when they perform Spinifex Gum at the Barbican Centre in London.
Marliya is made up of children who were also members of the Gondwana Indigenous Children's choir.
Spinifex Gum, which will be performed in both Yindjibarndi and English, was composed by the Cat Empire's Felix Riebl and Ollie McGill with Yindjibarndi Traditional Owners from the Pilbara.
The songs explore the political, social and environmental issues facing Aboriginal and Torres Strait Islander people in Australia, including incarceration, deaths in custody and land rights.
Yindjibarndi man Michael Woodley was one of the collaborators on the first Spinifex Gum project, sharing his stories, cultural knowledge and language with Riebl and the choir.
"He started to involve me in the project with our language and translating and teaching him and the other crew about how to speak and pronounce our language and that's how it started," he told AAP.
"One project became two, and then another ... we've put together three albums of Spinifex Gum now."
Spinifex Gum premiered in Adelaide in 2018 and has since been performed at every major arts festival across Australia.
The London performance will be the Marliya choir's first before an international audience.
Marliya chorister Stephanie Paul said that while she's excited to be performing at the Barbican, it's also nerve-wracking.
"To be going and sharing these stories and the real lived experiences and injustices that our people face ... on a world-renowned stage is just really special," she said.
"I feel a big sense of responsibility."
Mr Woodley will travel to London with the choir as a cultural custodian, supporting and guiding the young singers during the tour.
He said it's exciting but surreal for the stories and language of his Yindjibarndi people to be performed at the Barbican.
"To have our language go to the place where our country's identity, from a colonial point of view, was indoctrinated from ... and for the choir to sing about our language and stories, it's an honour and a privilege," he said.
Spinifex Gum combines music, stories and language with dance and visuals, and is conducted by Lyn Williams and choreographed by Deborah Brown.
Ms Williams said it would be a "great experiment" to see how an international audience would react to the show, which draws such emotion from Australian audiences.
"There are themes of sisterhood and togetherness and working together, which are universal and then there are themes which relate more directly to First Nations issues," she said.
"They always get a standing ovation (from Australian audiences) but we don't know whether that will happen in the UK, we don't know whether they'll connect quite as directly and emotionally to the material in the songs."
But Ms Williams said the girls and young women in the choir always share the important stories of the Pilbara in an extraordinary performance.
"They perform so well because they really believe in what they're singing ... that's what elevates them to this incredible standard that they reach, which astounds everybody," she said.
"They want to do an incredibly good job of telling these stories because the world needs to hear these stories."
Marliya will perform Spinifex Gum at London's Barbican Hall on October 6.
