I am an idiot

100% happy working with this PRO over 15 years. Throughout this time I could testify his artistry as a engineer and record producer. That's Brendan Duffey, satisfaction beyond words.

O MELHOR de todos!!! Sou fã número 1 👏🏻👏🏻

More than satisfied with how Brendan mastered our heavy metal album!

I had an awesome time recording my first album, 'BOO!!', with Brendan. I'm sure that my fellows Billy Sheehan and Mike Mangini will agree with me.. He's a professional master mind and very good friend! 5* for sure ;)

A large part of my success has been the great engineers that I have
worked with while recording in Sao Paulo. Brendan Duffey is a professional in
every way. He is fast on the keys, his ideas are brilliant and he works well
with artists. Thanks to the internet we're still working together as always.

Brendan has produced, mixed and mastered one album for my rock n roll band Bastidores, and has mixed & mastered the two others. He is amazing, both as a professional and a friend. I have learnt a lot with him, in many ways. Brendan, you rock!
