CALDERO SOUND Caldero Sound — Remote Mixing & Mastering for Modern Metal

Caldero Sound specialises in rock, metal, metalcore and alternative music — genres that demand visceral weight, power, and depth. I don't just specialise in genres; I specialise in sonic impact. If you're looking for an aggressive, world-class sound and refuse to settle for mixes that feel generic, sterile or lifeless, that's exactly my territory.

Sessions run on high-resolution, real-time audio streaming via Muse Sessions: you sit in your own listening environment and hear exactly what I hear in my studio, as I work. No bouncing emails back and forth with confusing notes — it's an immersive, collaborative experience where we make the critical aesthetic decisions together, protecting the emotional core of your music.

There is no fixed menu — every project gets a tailored sonic production proposal. First you tell me about your record, then we jump on a quick call so I can understand your goals, your release plans and what success looks like for this record, and you get a proposal built around your goals — not a rate card. That's how I make sure you never pay for things your record doesn't need.

Quality isn't something I rush.

Most singles are completed within 1–2 weeks, although timelines vary depending on the scope of the project and any revisions along the way. EPs and albums are scheduled individually.

Because I only take on a limited number of artists at any given time, I recommend getting in touch as early as possible if you're working toward a release date.

Once your project is confirmed, I'll send you a simple preparation guide before we begin, covering everything I need. Typically that's your multitracks or stems, your latest rough mix, and any reference tracks or notes that will help me understand your vision. If you're not sure how to export your session, I'll walk you through it — no tech anxiety required.

Every project includes the refinement needed to get the record release-ready. Rather than counting revision rounds, the focus is on making the right decisions as efficiently as possible together in real time by using Muse Sessions. Most decisions are resolved there and then, so lengthy revision chains are uncommon.

If the project changes direction after work has begun—for example through new recordings, arrangement changes, or replacement files—any additional work will be discussed separately.

Caldero Sound is based in Cambridge, UK, and works remotely with artists worldwide. Whether you're across the street or across the world, the experience is designed to feel as personal and collaborative as if you were sitting in the studio.
