Jon Rezin is a Grammy-winning mix engineer, producer, and mastering engineer who has spent over two decades shaping records that move people. His credits read like a global tour of contemporary music: Bad Bunny, Lady Gaga, Karol G, Burna Boy, Anitta, Ricky Martin, NCT, EXO-CBX, and dozens of artists across pop, Latin, K-pop, and J-pop — alongside hit film and television work, including The Unofficial Bridgerton Musical (Best Musical Theater Album, Grammy 2023) and The Masked Singer. He started in NYC jazz rooms, where the technical discipline of capturing a live performance in a single take taught him the lessons that still guide his pop and urban work today: phase, space, and a respect for what's actually happening in the room. From there, he moved into pop, racking up over 1,200 mixed tracks, 4 billion+ streams, and verified chart placements across more than 25 territories. Today he works remotely worldwide. He's fluent in stereo, immersive Dolby Atmos, and broadcast — a combination that puts him on a short list of engineers trusted with the biggest productions of the year. His Atmos work has been featured by Apple Music, Tidal, and Amazon. He's mixed live broadcast events watched by hundreds of millions, and intimate vocal-and-acoustic sessions with the same conviction. Beyond the studio, Jon is a regular consultant for labels, engineers, and managers — distilling 25 years on every side of the music business into 1-on-1 sessions that pay for themselves. He believes the difference between a good record and a smash comes down to taste, judgment, and the thousand tiny decisions no plug-in can make for you.
