Liam Annert

Sound Designer

Ask him about AFL and he won’t shut up. Mention NRL and he’ll nod politely while still thinking about AFL. That’s because we plucked him from the laneways of Melbourne to join the Rumble team. Having grown up in a record store in one of Melbourne’s famous districts, he wrote music as a solo artist during his early years before discovering sound design and joining the advertising and film industry. After finding his calling, he’s gone on to become an award winning sound designer with an ear for detail and his sounds can be heard on campaigns for some of the worlds biggest brands. Liam is a big advocate of pushing the boundaries, developing the skills to create immersive soundscapes for TV, cinema, 360° and VR. We’re very glad he’s made the move further north so we can slowly develop his tan and take him to bars that aren’t hidden.
