Decked out in identical utility gear and sporting enough lyrical artillery to frighten all of middle America, N.W.A quickly upended hip-hop tradition with Straight Outta Compton. One of hip-hop's crucial albums, it was a bombastic, cacophonous car ride through Los Angeles' burnt-out and ignored hoods. Dr. Dre's busy funk production lent the proceedings a carefree, unhinged air, and the lyrics, mostly written by Ice Cube, were powerful audio verite, especially on songs such as "Fuck Tha Police," "Express Yourself" and "Dopeman." N.W.A's broad influence became apparent three years later, in 1991, when Billboard adopted SoundScan technology only to learn that the top slot on the pop album charts didn't belong to Paula Abdul but to these Compton, California, thug arrivistes (sans Ice Cube, who'd left the group due to financial differences). Niggaz4life wasn't quite the barnstormer its predecessor was — it was less textured both sonically and politically — but its success showed that the boyz in the hood weren't to be taken lightly ever again.

“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.
