Emperor X is a noise pop/folk music project headed by American musician Chad R. Matheny. The project often performs and records with little more than Matheny on an acoustic guitar and a dynamic microphone, but sometimes also employs large groups of musicians on percussion instruments, various electronic noisemakers, brass/woodwind/string ensembles, and traditional rock instruments.

Emperor X tours across the United States regularly and performs around the world as well, including tours in Mexico, Canada, Australia, the United Kingdom, and the European Union.
