Tone Aston

Creative Director / Sound Designer

As a kid, Tone’s dream was to play guitar for pretty much any glam metal band that would take him. Since he can’t play guitar, none did.
Fortunately he made his way in to sound design where he’s been sharpening his craft on award winning campaigns ever since. His dedication to the art of sound has seen his reputation spread from local to international agencies and production companies alike.

While he loves creating beautiful soundscapes and directing talent to get the perfect read, his greatest career achievement has been bringing Rumble Studios to life with Johnny Green. Tone has recently stretched his wings to co-create the children’s cartoon series “Kazoops”, currently in production for worldwide distribution through ABC Australia, BBC UK and Netflix.

Johnny Green

Creative Director / Composer

If there’s one thing Johnny loves it’s good food and wine… And 80’s trivia and playing Galaga and golfing and skiing and… Although, a man of many passions, none can rival his love for music.

Cutting his cloth at some of Sydney’s top-shelf audio production companies, Johnny fine-tuned his skills when he relocated to New York City, composing music for some of the world’s heavyweight advertisers such as Unilever, Nike, Visa, and AT&T. After returning home to the sunny shores of Sydney, he teamed up with Tone Aston to launch Rumble Studios.

An award winning composer, Johnny has a passion for all things sound and constantly explores new techniques to apply to his artistry. An electro-acoustic artist in his spare time, Johnny sports his releases through Love F.A.M.E Records, Los Angeles.

Nathaniel Joyce

Sound Designer

“It’s like seeing with my ears.”
– New York Times
“Wait… What just happened?”
– Sydney Morning Herald

Born from an egg on a mountaintop, he’d defied the heavens by eating many of the holy peaches and became immortal. As punishment, a mighty Buddha imprisoned him under a mountain for 500 years to learn patience.

He was finally released by a Monk of ambiguous gender and accompanied him/her on a pilgrimage across ancient China to India in search of the Holy Scriptures. Joined along the way by a pig man and a fish man, the unlikely team battled many foes both natural and supernatural.

It was during this unforgiving apprenticeship he learned not only moral lessons based on Buddhist and Taoist philosophies, but the ancient art of putting sound to picture. However, Sound Design isn’t all just stick fighting and parables; it’s a rabbit hole of mystery and intrigue to which Nat has dedicated his life.

With over 2,000 years experience, Nat cannot only breathe life into your production, but breathe into his fingers and summon a small pink cloud to carry off onto untold adventures.

Liz’s first job out of high school was playing with dead fish at the Australian museum and she’s come a long way since then. Growing up the in the country gave her a sense of adventure and she spent most of her early adult life trekking across the globe, gaining worldly experience before returning to Sydney and falling into audio post production.

Spending almost five years at Stellar Entertainment, Liz has honed some serious skills in talent casting by listening to voice over demos just for fun, always looking for the ’new sound’. She is insanely organised, loves making excel spread sheets look pretty and likes to think she’s the voice of reason but is usually the devil on your shoulder.

Facilities Manager

Tam enjoys the satisfaction of making lists. Lists of music she loves, lists of life goals, lists of places she has always dreamed of going (like NYC and Graceland).
