Mario Semi is an Indonesian-born, Netherlands-based acoustic artist who transforms soul, funk, reggae, and blues into rich live performances using only his voice, guitar, and a loop station. Layer by layer, he creates hypnotic grooves, warm harmonies, and rhythmic textures that blur the line between solo performer and full band. Inspired by Bill Withers, Khruangbin, The Meters, and Black Pumas, his sound is intimate, groove-driven, and unmistakably soulful.
