Anthony Tillmon Williams was an American jazz drummer. Williams first gained fame as a member of Miles Davis' "Second Great Quintet," and later pioneered jazz fusion with Davis' group and his own combo, the Tony Williams Lifetime. In 1970, music critic Robert Christgau described him as "probably the best drummer in the world." Williams was inducted into the Modern Drummer Hall of Fame in 1986.

Jazz fusion is a popular music genre that developed in the late 1960s when musicians combined jazz harmony and improvisation with rock music, funk, and rhythm and blues. Electric guitars, amplifiers, and keyboards that were popular in rock and roll started to be used by jazz musicians, particularly those who had grown up listening to rock and roll.
