Justin Teasdale - Sound Designer

I have known Rob Summers for over 20 years and during this time we have worked on many productions in many different capacities. 

I was his No 2 on a number of touring productions, we have both worked as freelance sound engineers together and more recently he has operated shows that I have sound designed. 

I believe him to one of the best operators I have had the pleasure to have worked with. He has always shown a high degree of passion for this role and subsequently for any production he has been apart of. This coupled with his vast experience makes him, in my opinion, a valuable asset in any sound department. This is why when “Songs for Nobodies” was confirmed to have a West End run myself and Tony Gayle decided he was the best man for the role. 

His contribution has been consistently of the highest standard and has helped make this production sound as good every night as it did on the opening night.

About Justin Teasdale

Justin Teasdale started his career as a fully trained Audiologist and spent 5 years testing, diagnosing and prescribing hearing aids, for people with hearing difficulties. During this time he also had a part time job as a stage hand at the Blackpool Grand Theatre.

Once he realised had been bitten by the show business bug he decided to leave Blackpool and worked two Pantomimes as an ASM, one of these shows culminated in me playing the rear end of a Panto Cow. 

It was at one of these Pantomimes I met "The Grumbleweeds" who later offered me my first job as a Sound Engineer.

With the help of Rob Summers, Justin have managed to sustain a 20 year career in Professional Live Sound, working my way from Radio Runner to Sound Designer. He have managed to transfer a lot of my understanding of how the human ear works and the physics of sound to this career. 

Here are a few highlights of Justin Teasdale's Work. He toured with the following Musicals - Joseph, Annie, West Side Story, Fame, Chicago, Seven Brides for Seven Brothers, Beauty and the Beast and Matthew Bourne’s Highland Fling. He then operated Phantom of the Opera for 2 years in London’s West End and also worked for The English National Opera as a sound technician at The Coliseum, London. 

Teasdale was fortunate to secure a short term contract at the BBC World Service where he worked as a Studio Manager to cover the Jubilee, the Olympics and also help with the relocation of broadcasts from Bush House to New Broadcasting House.

Last year he started working as a Technician at the Barbican, a 2000 seated concert hall, where I got to work with many International Artists and the London Symphonic Orchestra. 

His recent Sound Designs were for the Sound of Music in Egypt and Lebanon.

Justin helps manage the Audio Cartel website with his good friend Tony Gayle. Their aim to raise standards by being able to offer the right level of experience to each role ensuring a happier environment for all, including the sound team. With our combined knowledge we are able to offer a quality package on most budgets to make the best sounding production possible.
