The first thing that must be said about the Rolling Stones’ 1971 album Sticky Fingers—which is being re-released this week in one-, two-, and three-disc editions, depending on how deep you want to wade into your own pockets and “previously unreleased” marginalia—is that it opens with the most morally vacant piece of music to ever hit the top of the charts. “Brown Sugar,” which in spring of 1971 became the Stones’ first U.S. No. 1 hit since “Honky Tonk Women” two years prior, is a rollicking and shockingly blithe rumination on slavery and sexual violence that unfolds over the greatest Keith Richards guitar riff that Keith never wrote (the riff, and the song, are Mick Jagger’s creation). The song’s Wikipedia entry describes it as “a pastiche of a number of taboo subjects, including slavery, interracial sex, cunnilingus, and less distinctly, sadomasochism, lost virginity, rape, and heroin” (quite a collection of links between those commas); in a 1995 interview with Jann Wenner, Jagger himself summed it up as “all the nasty subjects in one go.”
