Keith Morris is 55 years-old, a fact that's hard to process when listening to Off!'s explosive punk rock. It's been over three decades since he sang on the first recordings by L.A. hardcore's founding band Black Flag, and years since anyone paid attention to his own thrash warhorse Circle Jerks, but his deranged vocal attack remains pure. This collection of 2010 EPs by his most recent band perfectly recapitulates Flag's searing attack, from the scabrous riffs and distortion to the cover drawing by SST Records artist Raymond Pettibon. If titles like "Fuck People" and "Full of Shit" skirt self-parody, the frothing-wombat energy Morris brings to them is serious as a skateboard upside the head.

“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.
