It came at a time of great emotional turmoil and change, as the band's founder, Brian Jones, had died during the period of the album's recording. Undeterred, the Stones delivered one of their very best records, Let It Bleed. Randy Renaud has the story behind it for its 55th anniversary on this week's edition of the Chronicles of Rock.

Randy Renaud, with help from the man who organized the photo shoot, has that wild story on this week's edition of the Chronicles of Rock.
