Emperor X has been played on NTS shows including The Sam Wilkes Radio Hour, with Erica Western Teleport first played on 23 June 2023.

Emperor X is a pop/noise/folk music project headed by American musician C. 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.

The lyrics of Emperor X songs have been described as simultaneously "hallucinatory" and "precise," and discuss subjects ranging from plate tectonics ("A Violent Translation of the Concordia Headscarp"), paramilitary religious fanatics ("Allahu Akbar"), the nature of time as it relates to car accident casualties and the 2009 Port-au-Prince earthquake ("Defiance (For Elise Sunderhuse)"), failed attempts to fix broken air conditioners (“Compressor Repair”), and mass transit ("Everyone in Jacksonville", "Right to the Rails" and "Edgeless"). Emperor X tours the United States very frequently, and has completed several small tours internationally including trips to Mexico, Canada, and Australia.
