music industry experts with proven experience

Broken Horn Studios was founded in 2010 by musician William Mandell, with a focus on live performance recording. 


Over the years we have expanded our services, client base and network.  Our portfolio now includes commercial music, feature film mixing, audio books, podcasts and original music production. 

Check out the stories of our team members below. We have performed and produced music all over the world for both live and studio projects. There are many people not listed here (studio musicians, freelancers, etc)  that work with us and add their expertise in various disciplines. 


Growing up in a working class family on the SF peninsula, it was a big investment when William's parents bought him his first musical instrument – a trumpet.

At his very first official band practice back in middle school, our founder William set his trumpet case down behind his dad's car to unload stuff into a friends garage.   As William went inside, Dad started the car and backed up – thoroughly flattenening the horn.  He and his Dad were devastated.  Fortunately, they had purchased the insurance package offered by the store!

This poor trumpet is the inspiration for our name – reminding us that while 'things' come and go – the music lives on!
