paragraph_text: Jazz fusion
  
  In the late 1960s and early 1970s, the hybrid form of jazz-rock fusion was developed by combining jazz improvisation with rock rhythms, electric instruments and the highly amplified stage sound of rock musicians such as Jimi Hendrix and Frank Zappa. Jazz fusion often uses mixed meters, odd time signatures, syncopation, complex chords, and harmonies.
  
  According to AllMusic:
  
  ... until around 1967, the worlds of jazz and rock were nearly completely separate. as rock became more creative and its musicianship improved, and as some in the jazz world became bored with hard bop and did not want to play strictly avant-garde music, the two different idioms began to trade ideas and occasionally combine forces.
