... That Joni Mitchell has already proved itself (including with Jaco Pastorius live), but then the appeal of these images by Herbie Hancock would be gone. Most of the pieces come from Joni Mitchell and win by the diversity of performers. A great idea Hancocks with a successful compilation of singers such as Norah Jones, Tina Turner, Leonard Cohen and Joni Mitchell herself. Plus a congenial band. They are all musicians in a class that does not have (more) necessary to prove by intrusive technically virtuosic performances, how good they are, they do it discreetly. Beautiful music! - But nothing for fans who maybe something like a Pastorius-Groove expect.
