When we settled on Town Hall as the venue for the Festival of Dangerous Ideas (FODI) 2020, my first instinct was to consider a choir. The venue lends itself to this so perfectly and the image of a choir – a group of unified voices – struck me as an excellent symbol for the activism that is defining our times.

I attended Spinifex Gum in Melbourne last year, and instantly knew that this was the choral work for the festival this year. The music and voices were incredibly beautiful but what struck me most was the authenticity of the young women in Marliya Choir. The song cycle created by Felix Riebel and Lyn Gardner for Marliya Choir embarks on a truly emotional journey through anger, sadness, indignation and hope.

A microcosm of a much larger phenomenon, Marliya’s work shows us that within these groups of unified voices the power of youth is palpable.

Every city, suburb and school has their own Greta Thurnbergs: young people acutely aware of the dangerous reality we are now living in, who are facing the future knowing that without immediate and significant change their future selves will risk incredible hardship.

In 2012, FODI presented a session with Shiv Malik and Ed Howker on the coming inter-generational war, and it seems this war has well and truly begun. While a few years ago the provocations were mostly around economic power, the stakes have quickly risen. Now power, the environment, quality of life, and the future of the planet are all firmly on the table. This has escalated faster than our speakers in 2012 were predicting.

For a decade now the FODI stage has been a place for discussing uncomfortable truths. And it doesn’t get more uncomfortable than thinking about the future world and systems the young will inherit.

What value do we place on a world we won’t be participating in?

Our speakers alongside Marliya Choir will be tackling big issues from their perspective: mental health, gender, climate change, indigenous incarceration, and governance.

First Nation Youth Activist Dujuan Hoosan, School Strike for Climate’s Daisy Jeffery, TEDx speaker Audrey Mason-Hyde , mental health advocate Seethal Bency and journalist Dylan Storer add their voices to this choir of young Australians asking us to pay attention.

Aged from 12 to 21, their courage in stepping up to speak in such a large forum is to be commended and supported.

With a further FODI twist, you get to choose how much you wish to pay for this session. You choose how important you think it is to listen to our youth. What value do you put on the opinions of the young compared to our established pundits?

Unforgivable is a new commission, combining the music from the incredible Spinifex Gum show I saw, with new songs from the choir and some of the boldest young Australian leaders, all coming together to share their hopes and fears about the future.

It is an invitation to come and to listen. To consider if you share the same vision of the future these young leaders see. Unforgivable is an opportunity to see just what’s at stake in the war that is raging between young and old.

These are not tomorrow’s leaders, these young people are trying to lead now.

Tickets to Unforgivable, at the Festival of Dangerous Ideas on Saturday 4 April are on sale now.
