Matheus Braz is a Brazilian sound and mixing engineer best known for his contributions to Beyoncé's studio albums Renaissance and Cowboy Carter, winning a Grammy Award for the latter from two overall nominations.
[1][2][3] Braz immigrated to the US from Brazil and began his career working as a sound technician on cruise ships.
After some time, he returned to college to study recording and, after graduating, moved to New York during the pandemic.
[4] Braz was soon hired by the QUAD Recording Studios as an intern.
In an interview with Forbes Brazil about his early development in the music industry, he described his early days working at QUAD involving “clean[ing] a lot of bathrooms, floors and cigarette ash from the soundboards... [, but] in the meantime, I used all my free time to learn how to use the equipment and improve as an engineer.”[4] After a few months in the position, he landed an assistant engineer position and decided to move to Los Angeles with his wife, after the owner of QUAD Studios put him into contact with Stuart White (Beyoncé's lead recording engineer), a good friend of the studio owner who needed a sound engineer assistant at the time.
