Producer / Mix and mastering engineer / Mentor

Make the music you hear inside.

I’m Jacob Leone. I make heavy music and electronic bass as Jack.Lion, mentor producers one on one, and help artists finish records that still sound like them.

Personal guidance for the music you’re actually making.

We start with your sessions, your references and the sound in your head. Then we listen together, make decisions together, and build the judgment that lets you keep going on your own.

Personal guidance

Feedback shaped around your music, your experience and where you get stuck.

Practical listening

Hear what changes, then understand why. Technique always tied to a musical decision.

Creative instinct and technical craft from someone still making records.

Everything here comes from the same place: making music. Heavy textures, electronic bass and extended-range guitar. Making my own records keeps my ears honest, and it shapes how I treat yours.
