Professional Audio Services
Mixing & Mastering
Your track — balanced, polished and mastered until it sounds the way you hear it in your head and competes on any platform. Stems, rough mix or an old recording: send what you have.
Arrangement & Production
A riff, a voice memo, a rehearsal take — that's enough to start. I build full arrangements around your idea: guitars, bass, keys, drums, strings. Any genre, from one added instrument to a complete production.

About me
I'm Serhii Lazariev - guitarist, vocalist, and music producer based in Warsaw, Poland. Blues-rock, funk, jazz-rock, indie — I've been in it long enough to know what makes a recording feel alive.
Send me what you have — a phone recording, a guitar sketch, a half-finished demo. We figure out together what the track actually needs. Mixing, mastering, arrangement, new parts. Sometimes a full overhaul, sometimes just a few touches.
