Superb track by Jimi Hendrix, played both with the Band of Gypsys and the post-Gypsys line-up of The Jimi Hendrix Experience. Appears on a few live bootlegs, only official recording is from the 1969/70 live album Band of Gyspys, recorded live at the Fillmore East on New Year's Eve.
The track has quite a simple theme: violence only breeds more violence, and behind it all we're similar people. Asides from being a bloody good tune, it features Hendrix's most expressive guitar solos, intended to communicate the chaos of war and human suffering. These attracted the attention of the 'serious' music establishment, who had previously though Hendrix was just another rock musician. Miles Davis was apparently particularly impressed, and was trying to arrange session work with Hendrix just before he died. The track also features incredibly violent drumming, featuring a machine-gun snare roll that stadium rock would later make so infamous.
