Blue and Lonesome, the 2016 album of Rolling Stones blues covers, reminded everyone of the World's Greatest Rock and Roll Band's true musical beginnings , despite the many sea changes the band has endured. Those roots have remained a reassuring constant, though it's difficult to imagine any era when the bulk of the Stones' repertoire weren't Jagger-Richards originals. That's precisely the era covered by The Rolling Stones On Air. Of the 32 tracks on the 2-CD deluxe version, compiled from various 1963-65 BBC radio performances, many of them bootlegged over the past few decades. This marks their first official release.
