Jazz fusion began in the late 1960s in the United States. In the late 1960s jazz musicians such as Miles Davis and a band called The Tony Williams Lifetime began using electric instruments such as electric bass and electric piano in their jazz music. As well, jazz musicians began adding rhythms or beats from soul music, rhythm and blues, and rock music into their jazz music. Two important jazz fusion albums are "In a Silent Way" and "Bitches Brew."
