Mark C. Slee



Mark C. Slee's visual art is built around structured systems of addressable LED lights. Drawing on a background in computer programming, he develops algorithmic patterns inspired by both organic and mathematical process, employing procedural motion, subtle variation, and evolving shifts in form and hue. The work deliberately avoids tropes of dystopian futures or mechanistic expressions of technical function. Rather, Slee explores the nuanced boundary where light exudes a vibrant personality, transforming perception into meaning. The meeting of the natural and synthetic worlds is a space of imaginative exchange — a vivid experience that tickles both mind and soul.

These artworks are powered by a software framework Mark has developed called LX Studio.

Intricate grooves, dreamy textures, playful whimsical bounce. Over the course of an electronic music obsession more than 20 years strong, Mark Slee has evolved a deep musical style that reflects a unique personality, blending intuition and introspection with a methodical approach to production and curation.

Fully committed to digging the troves of modern dance music, Slee aims to uncover releases that stand out. His monthly mix show on Proton Radio showcases his discoveries, with over 100 mixes presented in the past decade. In 2016, Slee joined forces with musical partner Atish to form the label Manjumasi. Debuting with his own Nocturne Belle EP, Manjumasi celebrates quirky dance music that explores new territory without forgetting the dance floor. Beyond Manjumasi, Slee's original productions and remixes have been released on such imprints as Cityfox, Seven Villas, Lost Diaries, Cosmic Society, Magician On Duty, Nugget, Where the Heart Is, Proton Music, and more. In addition to regular appearances on his San Francisco home turf, Slee's style has earned him DJ sets in notable locales, such as Kater Blau and Sisyphos in Berlin, Cityfox in New York, and Robot Heart.

Since 2016 Slee has also been developing immersive, spatial audio-visual production tools for systems of up to 32 channels via Envelop. Notable live performances with Envelop include MUTEK.SF and FORM Arcosanti.
