In the lead up to National Reconciliation Week, a video of Goanna's iconic 1982 hit song, Solid Rock, being performed at the summit of the Sydney Harbour Bridge has been released.

Launched by Reconciliation Australia, the video sees Goanna's songwriter, Shane Howard, joined by the Sydney choir Barayagal and its leader, Gamilaraay songwriter Nardi Simpson, performing Solid Rock in celebration of reconciliation and justice for Indigenous people across the country.

It comes in the lead up to the 25th anniversary of the historic walk for reconciliation across the Sydney Harbour Bridge, which saw more than 250,000 people walk across the iconic Sydney landmark for reconciliation on May 28, 2000.

Lasting for nearly six hours, it was the largest political demonstration ever held in Australia.

With the theme of this year's National Reconciliation Week (NRW) being "Bridging Now to Next' Reconciliation Australia's chief executive, Karen Mundine, said whilst "we have come a long way," there is still a long way to go.

"Since the year 2000, there is now far greater awareness amongst Australians of the complexity and magnitude of First Nations' histories, cultures, and social systems and what we must do to reach a just, equitable and reconciled country," the Bundjalung woman said.

"This year is the third year of our NRW Voices for Reconciliation project, with more than 500 Australian choirs coming together to perform Solid Rock across Australia."

Described as "a damning indictment of the European invasion of Australia," Solid Rock challenges the official narrative of peaceful colonisation, appearing as the lead single from Goanna's debut studio album, Spirit of Place.

In an interview with Goldmine in May 2002, Mr Howard described his feelings after a visit to Uluru, which led him to write the song.

"I realised that this country that I grew up in, that I thought was my country, it wasn't," Mr Howard said.

"I had to reassess my whole relationship with the land and the landscape, and understand that we had come from somewhere else, and we had disempowered a whole race of people when we arrived."

As part of Triple M's "Ozzest 100", celebrating the 'most Australian' songs of all time in 2018, Solid Rock was ranked number 13.

Mr Howard said he was honoured to have the song performed by the Voices for Reconciliation choirs this NRW, and offered some advice to the singers.

"Sing it with gusto, sing it like you mean it, sing it like it matters, because it does," he said.

"Sing it like we are on a journey to somewhere much better because we are."

Mr Howard added: "It's all in the song and we still haven't faced up as a nation and proclaimed: 'Let us tell the truth, let us get on with the business of truth-telling, and then let's get on with the treaty business. Let's turn our anger into action.'"
