There were some music critics during the late 1960s who were saying that jazz had lost out and would never be an important part of popular music again. However, at this same time, something new was happening to rock as a result of the innovations, or creative talent, of the group Blood, Sweat and Tears that might cause these critics to be wrong. This group started blending jazz with their basic rock rhythms. Thus, among many rock fans, jazz began to be important again.

Rock became a rich variety of sounds, beats, and tricky melodies in the true tradition of jazz.
