If the fucked-amp squeal that constantly disrupts this show annoys you, imagine how pissed off Hendrix was. But this raw '68 soundboard tape is notable for a vicious live debut of "Voodoo Child (Slight Return)" and a long free-rock intro to "Purple Haze," with Hendrix wrenching howling fury from his guitar over an improvised bass-drums riot.

“Everyday People”

"Everyday People" managed to trailblaze in two different ways -- it was one of the first pop hits to deal with the subject of racial harmony, and it utilized Larry Graham's "slap" technique on the bass guitar, which would soon be copied by countless other bassists. Graham once said about his pulsating style, "I'd never done that before … that's where the freedom of creativity came in for the band, that we'd be allowed to do that." In 1978, the song's line "Different strokes for different folks" would be borrowed for the title of the hit television show Diff'rent Strokes.
