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.

Michael Gie

Executive Producer

Michael is a future NBA All-Star. While he waits for his final growth spurt he resides as Rumble’s Executive Producer and keeps the place running like clockwork.

After returning to Sydney, he combined his production experience with a passion for good music and good people, quickly developing himself in to a producer. Michael works closely with Rumble’s composers to ensure the music is of the highest quality and is focused on creating a rewarding client experience.

Sharika Toth

Senior Producer / Head of Casting

Some say she’s a Renaissance gal, others claim she’s a Shinobi by night, truth is, she can’t do backflips and has no patience for cryptic crosswords.

However, “Master Organiser, Producer Extraordinaire” has also been bandied about and one could say, “…’tis her calling!”.

To realise her raison d’etre, Sha swam through a vast vocational sea of all things – navigating deep leagues of music education/performance, arts management, and PR/communications (amongst other things), kept afloat by yars’n’yars at the ivories & making f-holes sing like sirens… she even explored the far reaches of Adland where she helped bring ideas to life as a music consultant to modern visionaries.

Beyond her love of long sentences, modal jazz, and an obvious affection for naval-inspired metaphors, Sha enjoys putting her (self-diagnosed) OCD to excellent use with an immaculate work ethic and penchant for bringing together the magic of sound, music, voice, and of course, the mighty Excel, to help all your audio post-production dreams come true.

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.

Mireille Abbott

Assistant Sound Designer

There are many strings to Mireille’s bow. Well actually, it’s a cello and it just has the standard four strings, but she plays them all masterfully on top of many other talents.

After completing her studies in Music, Psychology, and Sound Engineering on the sunny shores of South Africa, Mireille moved to the even sunnier shores of Sydney and snapped up a position as Rumble’s studio assistant.
She hikes & bikes & swims & sings… quite frankly, she makes everyone else look like sloths.
