Outsider music

Outsider music (from "outsider art") is music created by self-taught or naïve musicians. The term is usually applied to musicians who have little or no traditional musical experience, who exhibit childlike qualities in their music, or who have intellectual disabilities, mental illnesses or a nerve disorder. The term was popularized in the 1990s by journalist and WFMU DJ Irwin Chusid. Outsider musicians often overlap with lo-fi artists, since their work is rarely captured in professional recording studios.
