Meeanjin Songlinez delivered a vibrant showcase of Indigenous culture and creativity at Brisbane Festival at South Bank on Sunday.

Free to the public, the event drew a diverse crowd, highlighting the talents of Indigenous artists.

Directed by Shannon Ruska, a Yuggera-Toorabul man, and Kayleen Ruska, a Wakka Wakka/Kabi Kabi woman, the event was a celebration of Brisbane's Indigenous talent.

Headlined by Birdz & Fred Leone (Meeanjin Songlinez), cousins from the Ngulungbura Clan of the Butchulla nation, the show featured a mix of contemporary and traditional music.

"It's deadly to be performing here with Meeanjin Songlinez," Birdz said.

"Especially with my cousin, Fred Leone...we've got a really special project which were ready to start releasing this year.

"It's exciting just showcasing who we are as proud Butchulla people."

They performed a number of songs including Bagi-La-M Bargan.

Meaning 'fighting boomerang' in Butchulla, it's told from the perspective of a young man standing on Indian Head on K'gari (Fraser Island), watching Captain Cook sail past during Cook's expedition and exploration of Australia's east coast.

The song had caused a minor outrage on a conservative radio show after it was revealed it had been played at a Sydney public school.

Before their headline show, Birdz told the National Indigenous Times it was "funny that people are choosing to have a go at it (the song) four years later".

"I think that shows how important that song in particular is," Birdz said.

"The whole point of that song is to really educate people about the real history of this country and what really happened."

The line-up included performances by HAiZ, Dark Moods, Rochelle Pitt, H-Town, and Edgar Conlon, bringing positive energy and connection to the audience.

The event was more than a concert—more so a celebration of culture, heritage and Indigenous voices.
