Forty years is a mighty long time to hold a secret, but the seminal experimental art-rock band The Residents has succeeded in keeping their identities unknown for that remarkable stretch. So little is known about this performance collective that even their biggest fans debate whether the masked group is even made up of the same players these days as it was decades ago. For their latest “Talking Light” tour, The Residents have crafted a program of intense, unsettling story songs.
