About

It Starts at the Source.

I'm Sergey, a Moscow-based recording, mixing and mastering engineer. Since 2013, I've worked with artists across independent and commercial projects, from recording live classical concerts at Orpheus Radio to serving as Chief Specialist at Mosfilm Music Recording Studios.

I believe great records are made long before the mix. My focus is capturing the right sound at the source, then using thoughtful mixing decisions to give every element its place while naturally guiding the listener's attention. The result is music that feels effortless, translates everywhere, and stays true to the performance.
