In the middle of his 2010 concerts, Tom Petty interrupted the hits for a stretch of electric R&B and psychedelic jangle from his rebirth record, Mojo. This vinyl LP, issued for Record Store Day, is a crackling facsimile of the minisets inside those shows, including the tough freestyle strut "Takin’ My Time," the hard-blues-and-rave-up combo "I Should Have Known It" and the Allman Brothers-with-acid waltz "First Flash of Freedom." There is one non-Mojo nugget: a 1999 B side, "Sweet William," which suggests Bob Dylan's "Ballad of a Thin Man" juiced with the garage-rock helter-skelter of Count Five’s 1966 hit "Psychotic Reaction."

“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.
