A lot of overdubbed voicings by Mitchell sneak in here and there. This had not been typical of her earlier albums, and is one of the elements which lends to the somewhat richer atmosphere than its precursors have. Another strength is of course the musicians. Mitchell is backed up by extraordinary artists here, most of whom are best known from jazz and/or jazz-fusion bands. In addition to Jaco, Wayne Shorter (on soprano sax,) drummer John Guerin, Alex Acu?a, Don Alias, Manolo Badrena, and Airto (all on percussion) also contribute. Guitarist Larry Carlton guests on "Otis and Marlena," and Chaka Kahn sings back-up on "The Tenth World" and "Dreamland." Joni plays guitar and piano equally on this album. Something that really distinguishes this from all her other 70's albums, is the 16+ minute "Paprika Plains;" it features (in addition to Joni's voice, piano, and the band) an orchestra conducted by Michael Gibbs. The mood of the whole recording is really special. I believe the cover art suits the feeling very well. There's an interesting combination of freedom and what's obviously arranged, as well as an interesting balance between gravity and humor. The performance is freer here than on "Hejira," but still strongly recommended to fans of that album and to people interested in enchanting musical performances and sounds.
