Review by Gary Hill The discussion of progressive rock or not on this one is rather obvious. No, it's not prog. However, we generally put fusion under prog, and in many ways this is fusion. Additionally, if any jazz musicians have been open to new technologies and progressing music, Herbie Hancock has to be near the top of the list. This is a compilation of two older albums. Both of them make a lot of usage of vocoder on the vocals. These are both compelling sets, even if they lean towards more pop styles like disco and soul music.
