Machine Girl is an American electronic music project formed in 2012 by producer and songwriter Matt Stephenson in Long Island, New York, with percussionist Sean Kelly joining as a live member in 2015. Known for an aggressive fusion of breakcore, jungle, punk, and industrial influences, Machine Girl creates a frenetic sound that pushes the boundaries of electronic music through their relentless energy and experimental approach. Their output ranges from dizzying, hyperactive tracks that sample video game glitches and hardcore breakbeats to visceral live performances that blur the lines between dance party and punk show.

Over the years, Machine Girl has cultivated a devoted underground following, earning critical acclaim with releases such as "Gemini," "WLFGRL," and "U-Void Synthesizer," which showcase their genre-defying style and anarchic spirit. Their work is marked by an unyielding DIY ethic and a refusal to conform, making Machine Girl a vital force within the contemporary experimental electronic scene.
