Massive Voices

MassiveVoices - high quality castings and recording of voice artists.

We are Claudia Hesse and Heike Hesse.

Claudia is the founder and managing director of MassiveVoices. More than 25 years of experience in post-production have given her vast industry know-how.

Together with her mentor, Matthias Kratzenstein, she set up the casting department of the Hastings Audio Network before setting up her own international voice agency - Massive Voices - in London in 2009.

Since 2014 Amsterdam has been the home of Massive Voices.

Heike tried many things before she found her calling in music. She worked for various record labels, including Public Propaganda and Kontor Records (where she managed Scooter for many years). In 2004, after all that 'Hyper Hyper', she worked at Chocolate Blue as a Project Manager in Cross Marketing before opening her own music PR agency, idee deluxe.

She has been supporting since 2017.
