Jazz-rock, or more commonly known as Jazz fusion, is the combination of the rough staccato style of jazz in the smooth legato style of modern-day rock. Although it may seem this combination considering these styles of music are opposites, great artists such as Miles Davis and Herbie Hancock developed this style to give it a yin and yang effect. Where they accompany each other in perfect balance, this style of music was able to produce due to the new development of electric instruments such as the guitar and synthesizer. Following the swing movement in 1930, the Jazz fusion came out booming with Miles Davis leading the change with his song “In a Silent Way.” Following the release of this track, jazz fusion became one of the most significant jazz movements in history. Soon after Miles Davis, we see many other great fusion artists pop up, such as Herbie Hancock, John Mclaughlin, Tony Williams, and many more.
