We live in an age of postmodernism where all the arts, including jazz, are characterised by the replacement of the modernist avant-garde ethic of always trying for something new by a "pick and mix" selecting, often with tongue in cheek, of elements of old styles. Jazz musicians like Bird, Trane and Ornette were modernists who did something no one had heard before, but from the seventies, with the phenomenon of the backward-looking Scott Hamilton and Warren Vache, we entered the postmodernist stage which is still with us. Today's jazz players tend to put their styles together from pre-existing elements, whether from swing, bop, the avant-garde or world music. The result is a jazz which has ceased to be "progressive" and which can be labeled "neoclassical" when it enters the academy, a tendency particularly associated with the activities of Wynton Marsalis. Critics Alyn Shipton and Ted Gioia are two I can think of who promote this interpretation of the way things are today.
