ALANIS MORISSETTE: A BIOGRAPHY

ALANIS MORISSETTE: A BIOGRAPHY Paul Cantin (St. Martin's Griffin, $11.95) If Americans never grasped the full renown of Morissette's previous incarnation as a Canadian Tiffany, they will after reading this snappy, sympathetic bio. For here are countless, rather depressing vignettes about Morissette's cheesy teen-pop career and ''never before seen'' photos of her mall hair. But by detailing her prodigious natural talent, failed relationships, and transformative emotional crisis, Cantin, a journalist from Morissette's hometown of Ottawa, convincingly argues that the 13-million-plus-selling, Grammy-sweeping Jagged Little Pill sprang not from a calculated mage overhaul but a cathartic rebellion. Morissette's fans will appreciate the well-researched back stories to her confessional lyrics. B
