Artist Mi-kaisha delivers a soulful and hard-hitting vocal performance with her latest single, Eternity.

The Aboriginal and Tongan singer came in fierce with a message of empowerment, self-determination and resilience of Mob and describing Eternity as an anthem, celebrating culture and the unbreakable bonds of community.

"My hope is that Eternity resonates as a reminder of the strength and resilience of First Nations communities during such a challenging and momentous time in Australian political history," Mi-Kaisha said.

"A captivating fusion of R&B and soul traditions seamlessly integrated into a catchy, contemporary pop aesthetic, Mi-Kaisha says that this song represents a turning point in her artistry.

"I believe it represents wholly what I stand for as an artist, songwriter and most importantly as a Black woman.

"Eternity speaks to the lineage of strong, fierce Aboriginal and Pacific Islander women I was raised by."

Mi-kaisha is an advocate with a responsibility to actively support her communities and work against the systems that have perpetually oppressed First Nations and Pacific Islander Peoples in Australia.

"My existence is super political, but my music doesn't seem so at first glance," Mi-kaisha said.

"And I think there's power in that."

Growing up on the streets of Sydney's music scene, the soundtrack of her childhood included soulful 90s tunes and the island music of her father's Koori Radio hip-hop show "Island Hopping".

Mi-kaisha has just completed her undergraduate degree at the Clive Davis Institute of Recorded Music at NYU, receiving a Bachelor of Fine Arts in Recorded Music with a minor in Native America and Indigenous Studies.

Back on home-soil from Lenapehoking (New York City), Mi-kaisha will take the stage at the first SXSW Sydney this month to perform her latest single for an Aussie crowd.

Excited to be back on Country for this momentous cultural and artistic gathering, Mi-Kaisha feels equally passionate to be back on home soil for the major political event, the Indigenous voice to parliament referendum.

"I cannot wait to celebrate our homegrown talent at SXSW and the ways in which we're pushing boundaries, breaking moulds and just being deadly," she said.

Founded in 1987 in Austin, Texas, SXSW is best known for its conference and festivals that celebrate the convergence of tech, film, music, education, and culture. It will run in Sydney from October 18 to 21.
