Here at Firewater,

we work with talented

metal, punk, hardcore, rock, alternative bands/artists and help them turn their musical ideas into powerful reality that they haven’t been able to achieve before.

It is almost impossible to find a producer who will be passionate enough to push the limits of a band to the point of greatness, who can objectively make the right calls and not be blinded by being too close to the project.

“Billy knows his shit! 30+ years in the game, he knows how to get the killer tones, a great hook & the best song arrangement. From capturing great vocal performances to achieving the hardest guitar crunch & everything in between.”

James Jasta, Hatebreed

“Billy is one of the most musically diverse dudes that I’ve ever known, his vast knowledge of musical styles is what I think sets him apart from others. His ability to work with different kinds of vocalists, connect with them by building them up and making them a better artist than they were before, I think is unmatched. He is involved in every aspect of music from producing to recording and a dynamic live performer as well.”

Sendog, Cypress Hill

“Always on the right side of the tracks! Determination, full blown power and nothing short of it! Billy delivers with genuine passion and the results fall in the pit!”

Roger Merit, Agnostic Front

“I’ve worked with Billy a few times and am constantly amazed with his endless creativity! On top of adding in his 30+ years experience in the music industry, it’s mind blowing how he can help bring your game to a new level! He even got my new band Ocean Hills a record deal!”

Zoli Teglas, Ignite, Ocean Hills

“People should definitely go check Billy out. He’s bein in the game recording for a long time and is very easy to work with !!!! Go see him if you want that big sound!”

Hoya Roc, Madball

“Responsible for some very iconic records and music, you can be sure to get the full production package with Billy Graziadei, who’s roots cover a very wide spectrum due to growing up in New York’s 80’s and 90’s urban music scene. Having worldwide touring experience and talent to project the music and songs live is a major bonus most producers don’t offer. A Skilled writer, Pianist and BJ Black belt with no shortage of ideas,discipline and commitment to take our band Powerflo to the next level.”

Christian Olde Wolbers

Fear Factory, Arkaea, Powerflo, Violence

“We went to Billy because we wanted to work with a producer that would help us get to the next level. Not only did he help us find our sound, but he also helped us arrange our songs in a way that made each of them a unique musical journey. His sense of details and passion transpired at every level of the process. A record deal later, we can’t find any reason not to work with Billy again.“

Vincent Jacob, Yard of Blondes
