Here's a review of the Joni bio from this morning's Globe and Mail by John Doyle.
Life & Times: Joni Mitchell (CBC, 7 p.m.) is the big Canadian deal. A wonderfully rich and detailed study of Mitchell's life and music, it's way better than the usual Life & Times quickie biography. A two-parter (part two airs next week), it will later be seen on PBS as an American Masters special. Mind you, she is Canadian. It's a richly detailed assessment of Mitchell, with a lot of marvellous footage from Canadian TV over the years. Best of all, it has many interviews with fellow musicians who assess her honestly and, sometimes, ruefully. Mitchell herself is an utterly beguiling figure, sharp, witty and self-deprecating.
