‘Such a pleasure working with you, you got the best out of me!!!’ – Lorraine Stanley, Film and TV nominated actress.

‘I just wanted to say thank you so much for your time and patience with me. I think you are brilliant! I would love to work with you again!’ – Jessie Wallace, BBC Eastenders actress.

‘Music is a tricky endeavor in film. It requires a keen understanding of material as well as a sensitivity to moments. Mathieu recently scored my half-hour television pilot. And after working with him the past few months, I was continually impressed with his sense of the script, of the words on the page and the actors performing those words and what they might mean in terms of score. He takes direction well, especially from this not-so-musically inclined writer. And he’s a lovely, easy-to-work with artist and craftsman. High marks for maestro Mat Karsenti.’ – Hal Cantor, TV writer and producer.

‘Mathieu and I have worked together on numerous productions over the last few years. Mat is an absolute joy to work with and he is the first person I call when looking for a composer. He has a strong grasp on the briefs given and always manages to successfully interpret the overall vision of a show through his music. Mat’s working style is open and collaborative, he is fully engaged with all aspects of production and his passionate approach to any given project ensures he delivers unique and refreshing scores time and time again.’ – Rob Hyde, three times Bafta winner, TV executive and producer, Inkypocket Ltd.

‘Mathieu is on my list of go-to composers for my TV productions because he always delivers professional results in a timely manner, even last minute. Also, he is not afraid of going beyond the call of duty to provide extra options and fresh suggestions to ensure I get the music I need.’ – Jamie Rea, TV executive and producer.

‘I worked with Mathieu on 90 Degrees North, a short film that has been nominated for the European Film Awards 2016. During the finding stage, he churns out ideas at an incredible rate – knowing full well that defining the style is best done through hearing actual musical sketches, rather than simply talking about it. Our film is a grotesque modern fairy tale with horror elements, Mathieu proved to have a fine understanding for what the purpose of the music was and when to place it. His developing theme serves to describe the inner life and growth of the character. It was through his diligence, professionalism and acute understanding of the material that we came up with the right score. It is a delight to collaborate with Mathieu.’ – Detsky Graffam – film director and writer on ’90Grad Nord’, for K17 films.

‘During 2014 and 2015 I had the pleasure of working with Mathieu on the score for a feature documentary I co-directed. Mathieu is an absolute professional and working with him was incredibly easy. His understanding of conceptual briefs and ability to interpret the needs of the filmmaker are a perfect pairing to his incredible knowledge of music, composition and instrumentation. I wouldn’t hesitate in hiring Mathieu again, the final score was so much more than I could have ever hoped for, and really was the icing on the cake for our production. I thoroughly look forward to our next project together!’ – Anthony Peters, co-director and writer at Studio Imeus.
