Not hip to the concept of outsider music? Fear not. Irwin Chusid, author of Songs in the Key of Z, the Bible of this "genre," will enlighten you:
Outsider musicians are often termed "bad" or "inept" by listeners who judge them by the standards of mainstream popular music. Yet despite dodgy rhythms and a lack of conventional tunefulness, these often self-taught artists radiate an abundance of earnestness and passion. And believe it or not, they're worth listening to, often outmatching all contenders for inventiveness and originality...
