In the space of only about four years in the mid-1960s, Wayne Shorter put out about 7 albums, any one of which could have revolutionized jazz music. In my view, Speak No Evil is the best of them all (though the competition is incredible). Basically, jazz music entered a new and original phase through Shorter's compositions. In the '30s and '40s, people played swing and then bebop, which were "jazzed up" approaches to standard tunes. The '50s and early '60s saw a period of new jazz composition, and a self-conscious introduction of new styles that were centered around instrumental style rather than around standard tunes. These new styles definitely broke new ground, but they still were mostly built around virtuoso-style improvising that exploited the harmonic possibilities of the chord structure of a song. Though it is obviously indebted to this tradition, Shorter's compositions shifted the focus away from "blowing" and onto the beauty of the compositions. Playing these songs emphasized more the evoking of the appropriate mood and texture rather than just using them as generic platforms for playing the same scales and licks. Basically, these songs invited new forms of exploration--and for that reason they remain some of the most popular songs for contemporary jazz bands to play. This album, Speak No Evil, is a real pleasure to listen to, and that is true the first time and the five-hundredth time. This is one of the tiny handful of albums that can without question be called the greatest in the history of jazz. Everyone should have the pleasure of listening to this album.
