KC PORTER

"I’ve worked with some of the most talented engineers and producers in the business, but none have left as much of an impact on my music as Javier Valdeavellano (Javillano). His work ethic is unparalleled, and his engineering, mixing, and production skills are truly impeccable. He’s one of the few I would entrust my projects to wholeheartedly."
