João Vasco An amazing experience with João. With only some audio references, very short briefing from our part and sometimes vague information, he would always find a technical way to meet our requests. The final result of his mastering work went beyond our best expectations. Highly recommended! João Vasco Musician José Mira In a nutshell, João is a person who seeks to understand the overall vision of the project and above all, he is very involved in everything he does. He has a natural talent for musical composition and for all the remaining parts of the sound. It's always a pleasure to work with him. José Mira Director Renato Arroyo João Alves’s work is breath-taking, professional, efficient, and reflects the taste and panache that are also visible in the decoration that he has created for this space. Besides being very well equipped, the studio is comfortable and welcoming for the client. For those who are looking for the best mastering engineer for their music, João is the right choice. Renato Arroyo Director Hedisson Mota I have known João for his academic, artistic and professional portfolio long enough to attest to his unmistakable talent for audio production. He is profoundly knowledgeable about all the technological tools associated with the mastering process, and above all, he displays a respectable scope of musical culture. I appreciate his work ethics with respect to the dedication, rigor and perfectionist attitude that he bestows upon all the music he masters. He manages to hear critically every detail of the sound while contextualising the process in its artistic-musical dimension. And, as a good professional is not made just of talent and competence, João Alves is also recognised as an excellent human being. Hedisson Mota Teacher & Musician Francisco Santiago Working with João has been one of the most rewarding and fruitful partnerships with which I have had the opportunity to enter into in my professional activities of the numerous ensembles and orchestras that I’ve collaborated with. Rigor, method and strong and constructive critical listening and analysis are the pillars of João Alves’ work. Francisco Santiago Executive Producer at Lisbon Film Orchestra Nuno de Sá João Alves has been mixing and mastering the Lisbon Film Orchestra since 2014. Right from the first project, I’ve realized that he was a demanding professional. He always tries to respond with the utmost efficiency and rigor. After all these years he has managed to evolve even more, bringing technical characteristics of excellence while having the artistic sensitivity to understand the needs of his customers. Top quality! Nuno de Sá Conductor of the Lisbon Film Orchestra Pablo Rodriguez I was looking for mastering a jazz/classical/world duo album of violin & piano. After considering looking at many options, Joao was the right choice. He's a truly skilled professional that will deliver the final touch that your music needs. Communication was fast and precise. He brought great ideas that improved the record. I will totally recommend it for any acoustic type of music. Pablo Rodriguez Virtuoso violinist/Composer Surin Song João is a wonderful mastering engineer. He always took his best efforts in every process and delivered all the masters I wanted. I absolutely want to work with him again on my future projects. Surin Song Film Composer Nana J. Great mastering! Pays specific attention to detail and very engaging to work with. Went above and beyond to make sure the song got what it needed. Looking forward to working on future projects! Nana J. Songwriter Hugo Alves “Sweet!" (Mastering Studio), is the best word to defines João Alves’ work. It is a pleasure to work with is sensitivity and dedication to make a record sound as I wish, as it happened in the Morphosis Album. Currently the challenge is greater with the Algarve Jazz Orchestra, something that could not be going better either! Thanks João! Sweet! Hugo Alves Musical Director at Algarve Jazz Orchestra
