100 pop chart. The two Hendrix compositions, "Power of Soul" and "Message to Love", are also more structured and rehearsed songs. They represent Hendrix's new blending of funk, R&B, and rock together with a new lyrical approach. According to Shapiro, the lyrics reflect "a Jimi Hendrix who felt an increasing need to impart his compassionate vision of human potentiality [and a] move away from cynicism and bitterness". Cox and Miles provide strong instrumental backing, where the rhythm is "locked-in" or "deep in the pocket", a common feature of funk and R&B. (Nearly all of Hendrix's music, and contemporary rock in general, uses common or 4/4 time; "Manic Depression" (3/4 or 9/8), "Dolly Dagger" (5/4), "Stepping Stone" (8/8), and the slow blues ""Red House" and "Belly Button Window" (both 12/8) are among the exceptions.) Jazz innovator Miles Davis felt that Cox and Miles were the best rhythm section for Hendrix and freed him from the constraints of the Experience. Guitarist Jean-Paul Bourelly, who played with Davis, commented in an interview: "Machine Gun" is another song that Hendrix had spent more time developing. By the Fillmore East concerts, it became an extended guitar improvisational piece, which "would completely change the perception of Hendrix's capabilities as an improviser and musician", according to Shadwick.

He liked the way Coltrane played with all those sheets of sound, and played his guitar in a similar way". From Hendrix's dedication of the song "to all the soldiers that are fighting in Chicago and Milwaukee and New York, oh yes, and all the soldiers fighting in Vietnam", "Machine Gun" is as much about the late 1960s American race riots as the war in Vietnam. Guitarist Vernon Reid describes it as "like a movie about war without the visuals. It had everything—the lyrics, the humanism of it, the drama of it, the violence of it, the eeriness of it, [and] the unpredictability of it". In many commentaries about Band of Gypsys, "Machine Gun" is singled
