Jazz music can always surprise the audience about how it might sound, because jazz always shows its great flexibility in combining with other musical styles and its high acceptability regarding new ideas. “In its earliest form, jazz showed the ability to assimilate blues, rag, marching and other idioms.” In the contemporary era, some musicians have combined jazz with rock, pop music, free funk, etc. The works they created, which began to emerge in the 1960s, belong to a new genre called jazz fusion. Jazz fusion brought audiences a new kind of aesthetic experience and encouraged musicians of that era to create many special pieces. In “Bitches Brew”, Miles Davis mixes some rock elements with jazz music; in Out of Your Mind! and Weasels Ripped My Flesh, Frank Zappa created music that gives people totally different feelings even though both are jazz fusion albums; and on Weather Report's album Heavy Weather, they combined jazz with funk and R&B music and gave each member the opportunity to improvise. Jazz fusion, as a general concept, just shows people that music representing an idea of ​​combining characteristics of two or more types of music to create new and special works that have the musicians' personal icon and can better express emotions of musicians.

The musical instruments used in this song that respond to the rhythm section include a guitar. During the recording, a bass, a double bass, three drums, two electric pianos and a percussion were played simultaneously.

When recording the album, Davis focused on the spontaneous interaction between each musician, rather than giving many instructions on what they would play.
