Mizzmo is a name steadily carving out its own lane in the underground circuit. As a resident at the forward-thinking Mesmeric Sofia, Mizzmo has become known for sets that are as immersive as they are unpredictable-deep, rolling journeys that glide effortlessly between genres, never content with the obvious or the expected. With a crate full of sonic curveballs and a razor-sharp sense for timing, Mizzmo doesn’t just play tracks-he bends them into new forms, challenging dancefloors to think, feel, and move in fresh ways. Always one step ahead of the curve, this is an artist who refuses to sit still-and makes sure no one else can, either.
