I'm Jonny Castillo. This is where I share everything I've learned about making it as an independent artist.
Make Music. Build a Career.
I've spent over a decade making music, engineering records, and figuring out how to build something real as an independent artist. Most of what I learned, I had to figure out the hard way. Colorful Sound Studio exists so you don't have to figure it out alone. No gatekeeping, no fluff. Just real talk about the craft and the business — from someone still in it.
Welcome to Colorful Sound Studio. I’m glad you’re here.
This Is What I Do
My music. My clients' music. All made with the same care, the same room, and the same obsession with getting it right.
Your Questions,
Answered
What is Colorful Sound Studio?
It's an education and community platform built for independent artists who are serious about the long game. I share what I know about the craft, the business, and the real-world decisions that go into building a music career — through content, livestreams, and a growing community of people doing the same thing.
What is The Full-Time Artist?
It's my Skool community for indie artists who are done waiting for a break and ready to build something sustainable. There's a free tier — The Lobby — where you can get a feel for the community and access foundational content. The paid tier, The Room, is where the real conversations happen: deeper resources, direct access, and a group of artists who are actually putting in the work.
How can I work with you?
For music supervisors and music libraries: I work with a tight creative team covering writing, production, engineering, and content creation. If you've got a project that needs a full creative vision executed, reach out. We'd love to hear what you're building.
For independent artists: I'm selective about the projects I take on because I want to actually serve the music — not just run a session. If you've got something you're serious about, hit the Contact button and let's talk.
The Listening Room
A community for people who actually listen to music. One album. One room. Every month. Join The Listening Room — a free listening experience built for people who love music like we do.
The Full-Time Artist
For independent artists who are done waiting and ready to build.
Most artists are talented enough. What they're missing is a clear path, real resources, and a community of people who are actually doing the work — not just talking about it.
The Full-Time Artist is a paid membership community inside Skool built around one goal: helping you turn your music into a sustainable career. You'll get access to in-depth resources on the craft and business of music, a community of serious indie artists to learn from and grow with, and direct access to me — someone who's been in it for over a decade and is still building alongside you.
This isn't a course. It's not a coaching program. It's a room full of people who take their music seriously, led by someone who does too.
