The 4-cd Geffen set presents, repackaged and remastered, Joni Mitchell's post-jazz, return-to-pop period, from 1982 to 1991. True, Mitchell's 80s period is jazzier and more daring than conventional pop music, but these CDs nonetheless mark a major shift from the wordy and impressionistic jazz-rock fusion of her late 70s work to a simpler and perhaps more accessible pop-rock. By nearly anyone's measure these albums do not stand up to her finest work, the masterpieces Blue, Court and Spark, and Hejira. But their extraordinary production value (very appreciated by this fan if not by all), accompanied by some remarkable songs (Moon at the Window, Impossible Dreamer, My Secret Place and Cherokee Louise are the respective highlights, among others) make for intriguing, challenging and beautiful listening. Another highlight: the bonus demo of Two Grey Rooms, a track demonstrating better than any other found here (or perhaps before or since) what for me is the essence of Joni Mitchell's work: sensuality, desire, sophistication, love. I can't respond to another reviewer's claim that this set isn't adequately remastered. I detect a richer, fuller sound than the original CDs, and I'll have to leave it at that. The booklet contains extensive comments by the artist, some insightful, some spiteful, some amusing, all Joni.
