The locally based, globally minded music mag No Depression is calling it quits, effective with the May-June issue.

Cause of death: A dying music industry, whose endemic issues are finally reaching indie labels, who can’t afford to buy as many magazine ads as they used to.

For 13 years, ND has been the greatest chronicler of “alternative country,” “Americana,” and assorted other essential US/Canadian homegrown musics.

The big irony here: An institution dedicated to honoring longstanding or lost art forms, and to celebrating contemporary artists who keep those forms alive, is itself becoming history.
