Interview with Leo Frangioni
Q: Tell us about a project you worked on you are especially proud of and why. What was your role?
A: My proudest project up to date is my original album "low end bit station" by .lio. I took on every role for this project, seeing that the ideia for the entire .lio project is do everything myself. Everything from start to finish was made by me: the musical and visual concept, sound design, composition and arrangement, recording, playing (except for the horns on the first song), mixing, mastering, and visualizer.
Q: What are you working on at the moment?
A: Right now, I'm working on 3 projects besides taking on recording, production, and rehearsal sessions in my studio. The first is a co-production for a Hip-Hop/RnB album, in which my client (Novak97) created some scratch beats and hired me to finish and polish them, as well as record, mix, and master the entire project. The second one is mixing and mastering a RnB singer's (ASHIRA) album. The last one is mixing and mastering Victor Xamã's next album.
Q: Analog or digital and why?
A: Both, each one has their own value and they work best when they're together. Analog has more life, warmth, and feeling, while digital has more precision and faster recalls. Being able to use both on a daily basis is what took me from a good engineer to a great engineer.
Q: What's your 'promise' to your clients?
A: You will get the best version of your song I can possibly make.
Q: What do you like most about your job?
A: Being able to work with so many talented and accomplished people is what I most value about working with music. I have the chance to connect and have amazing exchanges with engineers, producers, session musicians, artists, videomakers, and many other people. I'm grateful for having the opportunity to learn with each one of them.
Q: What's the biggest misconception about what you do?
A: "There're too many buttons."
Q: What questions do you ask prospective clients?
A: Who/what are your references? What is your goal with your project? What do you most and least like about your project?
Q: What advice do you have for a customer looking to hire a provider like you?
A: The most important skill you should look for is the ability to listen to what you and your song needs.
Q: If you were on a desert island and could take just 5 pieces of gear, what would they be?
A: My laptop, Antelope Discrete 8, SSL VHD 4 Preamps, my Tagima P-bass, Stratocaster.
Q: What was your career path? How long have you been doing this?
A: I began making beats in 2016, when I started writing rap music. At first, I made beats just to have something to rap on, but that suddenly became my passion. Around 2018, I dove into the realm of music production (apart from beat making) and fell in love. Since then I graduated from Berklee College of Music and produced, mixed, and mastered several records for myself (I have 3 original projects: hip-hop; latin music; experimental music) and for clients. I recently opened a premium recording studio, quickly expanding my knowledge to analog and hybrid setups. I am now confident in my skill to lead any and all recording and mixing sessions that are presented to me.
Q: How would you describe your style?
A: Experimental, groovy, and mischievious.
Q: Which artist would you like to work with and why?
A: There are so many, but the first that comes to mind is João Bosco. He is able to create such marvelous atmospheres with the acoustic guitar, I would love to be able to engineer a record of his.
Q: Can you share one music production tip?
A: If you don't feel it, other people won't either.
Q: What type of music do you usually work on?
A: Mostly Hip-Hop, Rnb, and Brazilian/Latin music, but I have experience in Rock, Pop, Electronic, Dance, Jazz, Soul, and more.
Q: What's your strongest skill?
A: Being able to listen to the client, to the song, and to myself, and trust my decision-making enough to follow through the best way possible.
Q: What do you bring to a song?
A: I bring whatever I feel a song needs. If I hear something that is not there, or hear something that should not be there, I'll act upon that realization. That applies to both the creative and technical aspects of a song, in production and post-production. What I value the most in my work is preserving the original and real feeling of a song.
Q: What's your typical work process?
A: Each project or service requires a different process, but my macro process is analyzing and reviewing files, reference tracks, and briefing, followed by the actual service (ie. mixing), quality control and review (for mixing that includes listening in multiple levels and systems, for ADR that includes A/B comparing with the original), and finally delivery. If revisions are required, I'll do that lastly.
Q: Tell us about your studio setup.
A: My studio setup consists of a Mac Pro, Antelope Orion 32HD interface, Pro Tool Ultimate with HDX, SSL AWS 900+ SE console, and several outboard gears such as Avalon 373, Distressor, API 512c, Neve 1073 and Portico II, Clariphonic, Culture Vulture, SSL X-Rack, DBX 160A, and more.
Q: What other musicians or music production professionals inspire you?
A: I have inspirations from all around the genre spectrum. Some of them include J Dilla, MF Doom, João Bosco, Djavan, Quincy Jones, Sade, Flying Lotus, George Benson, Led Zeppelin, and more.
Q: Describe the most common type of work you do for your clients.
A: My clients revolve around three main types of work: music production, mixing/mastering, and audio editing/restoration. For music production, I can work remotely or on site, in São Paulo, Brazil, creating and recording songs. Mixing/mastering is done in my studio using analog gear and digital software. Audio editing/restoration is usually focused on podcasts and ADR dub.
