Troy Russell, the lead creative of Lost Histories, will be one of the artists taking to the stage for the opening of the new New South Wales Art Gallery.

The Biripi and Gamillaroi musician and composer will be joined by performers Leila Hamilton and Susie Bishop this month to share their music.

Russell describes Lost Histories as an archival study of the past and future of one's own personal story in which he, along with Bishop and Hamilton, encourage schools and children to keep a record of family stories.

"Lost Histories' ultimate goal is to get young children to speak about family history, but also to get schools to make a time capsule," Russell said.

"If it doesn't come to that then the individual child can make a memory box for themselves to keep, with bits of family history, something they will be able to cherish in time."

The songs from Lost Histories are based on Russell's own family history where he sings about everything, including a famous bushranger.

"Recently I found out I am related to a bushranger, her name was Mary Ann Bugg and she was the partner and wife of Captain ThunderBolt," he said.

Russell said Lost Histories is aimed at the younger audience. He hopes to spark their creativity and encourage curious investigation, inspiring them to take a journey of self-discovery.

After performing at the opening of the new library, Russell and his team will tour around Australia, visiting schools and introducing them to Lost Histories.
