The question of what is jazz and what isn't rages, dividing audiences, dividing musicians, dividing generations. For many, the real question is whether jazz, the most American of art forms, will survive at all. Rock 'n' roll groups dominate record sales and radio, and many jazz musicians, like Dexter Gordon , are forced to leave America in search of work. John Coltrane records prolifically and appeals to broad audiences before his untimely death at age 40. Saxophonist Stan Getz helps boost a craze for 'bossa nova' music.
Great singers celebrate the essential contribution of vocalists to the development of jazz.
The avant-garde movement creates innovative music but appeals to an increasingly limited audience. By the late l960s, jazz is struggling to find its way. In the early l970s, Louis Armstrong and Duke Ellington pass away. Miles Davis , after forming his most innovative acoustic jazz group, leads a movement of jazz musicians who incorporate elements of rock and soul into their music in an attempt to appeal to a wider audience. Jazz musicians continue to practice, perform, record, disagree, improvise and jam.
