Joa was truly wonderful to work with, and I was so pleased with the final sound of the Vinyl album! He took it to the next level. I appreciated how Joa cared so much about my music as well as my satisfaction with his work, he was super prompt, responsive, and kind - this makes all the difference when you’re working on your art. The whole process was very smooth and supportive. As a woman in the industry, I felt respected and uplifted in the best way, which can be a rare experience. I felt very lucky to work with Joa on this album.

As artists, part of the challenge in this business is being able to find the right resources to complete our projects. The music business is a tough place to navigate and trust is hard to find. When the time comes to send off your most prized possessions for mastering, choosing the right destination can be very difficult and stressful. After finding Star Frog Mastering, I no longer have to worry about that. Working with Star Frog has not only been a stress-free and hassle-free experience, it has become a pleasurable part of the process. Like a trusted friend or bandmate, they will help guide you through the process with great advice, incredible insight, and helpful information that will take your creations to the highest level imaginable. I’ve learned so much about this part of the process and it’s all because of the caring, dedicated, and personalized work ethic that Star Frog applies to every project. At the end of the day, your art is treated as if it was their own, crafted, nurtured, and treated with the utmost care. After almost two years of working with Star Frog Mastering, I can’t imagine my music in anyone else’s hands. I had no idea that a business decision would become such an honored friendship and that’s pretty hard to find these days. Save yourself the hassle and stop worrying about who to trust during the most important part of the journey…the master at Star Frog has your back!!

What Artists say about StarFrog''s hEAD engineer
Joa’s journey led him to master the art of mastering music. A unique skill set that is often misunderstood and under-appreciated. Even by engineers and artists in the industry. But Joa gets it. He knows how important the mastering process is for creating great sounding and feeling music and has studied with the best to become the best he can be. In addition to being a fantastic mastering engineer, he is also a singer, songwriter and ceremonialist, so he understands the art from the inside out. From the technical depths of adjusting a nuanced EQ curve, to writing a poetic and beautiful song, to his energetic and shaman-like sensitivity to the spiritual realms, Joa understands sound and vibration in a way that not many people do. And his devotion to healing and awakening is in everything he does.

Mastering can be an elusive art, and often downplayed or not understood in its importance to the final product. Joa’s approach engulfs my passion for blending live and electronic music, giving the overall master both the analog sonic grit while maintaining the clean heavy hit of a good electronic dance track. He is also a gem of a human to work with; quick, communicative, kind, and generous. We are all on the same team of making the music receivable as real sonic medicine for the soul.
