Production / Mixing & Mastering Studio Led By Jon Kong
Expansive Audio
Jon Kong is a producer and mixing / mastering engineer with over 15 years of experience rooted in the underground club scene and extended into global electronic music.
Coming up through house and techno, he built his reputation as the engineering and production force behind Leftwing : Kody, alongside extensive hands-on work with underground artists and labels where taste, groove, and longevity are essential. That club-focused foundation remains central to his work today, shaping an approach led by musical function rather than trends.
From this underground base, Jon has translated real-world credibility into large-scale commercial releases without compromising identity. His work has appeared on influential labels including Hot Creations, Solid Grooves, Repopulate Mars, Defected, Anjunadeep, and Armada, as well as major labels such as Sony, Columbia, Virgin, and Positiva.
His collaborations span club-focused artists like Michael Bibi, Patrick Topping, Hot Since 82, and Vintage Culture, alongside global and crossover acts including Lost Frequencies, Kelis, Nelly Furtado, and Mabel.
Across his career, Jon’s records have achieved multiple Beatport No.1 releases, received support from BBC Radio 1, KISS, and Capital, and featured on major Spotify editorial playlists — contributing to hundreds of millions of streams worldwide.
