During the pandemic, Kuba re-evaluated his life, organized his folders of music collected over the years, and came out as Cosaco DJ from the Laboratorio Tropical Crew – a Warsaw Sonidero deeply in love with and immersed in cumbia. Cosaco most enjoys playing dubby, dark, futuristic cumbias, cumbiatón, dembow, dancehall, neoperreo, Latin Tek, and Latin Rave. His sets mix genres, shift tempos, use samples, and often intervene in the structure of tracks. Kuba is also a beekeeper and a proud dog dad.
