"19th Nervous Breakdown" (1966)
A lyrical breakthrough, with references to drugs and therapy, "19th Nervous Breakdown" showed the Stones could pack sharp social criticism into headlong rock & roll. Jagger came up with the title phrase after five weeks of an exhausting U.S. tour. He spun it into lyrics about the trendy neurosis of posh London girls, sung over jagged Bo Diddley-style riffing. As the song fades out, Wyman uncorks a wild dive-bombing bass sound that ups the sense of harried intensity.
