An Address from the Jury President:
“There’s never been a more important time to future-proof our industry by discovering, elevating, and backing young talent. As the landscape shifts faster than ever, and the realities facing our industry grow more complex, we need new energy, new bravery, and new ways of thinking.
At its best, Young Drummers is exactly that: a platform where emerging creatives can push themselves, challenge conventions, and start shaping the future of our industry.
I’m honoured to step into the role of Jury President for the Young Drummers Competition at Golden Drum. Together with my fellow jurors, I’m looking forward to discovering work that feels bold, unexpected, and genuinely exciting—ideas that don’t just reflect where we are now, but where we’re headed.”
