Singer Taylor Swift. Even if you don't follow pop music closely, perhaps you have heard of her. Creative Commons photo by Ronald Woan, details here.
As I noted recently, the recent death of MC5 guitarist Wayne Kramer was a reminder of the amusing conspiracy theories about music that are a feature of Illuminatus!, including the claim that the popularity of the Beatles was a Communist plot.
Jesse Walker, no stranger to conspiracy theories or to pop music, has a new piece out, "Taylor Swift Is Just the Latest Subject in a Long History of Pop Conspiracy Theories." I don't want to spoil Jesse's best lines by quoting from it, just read it. Illuminatus! fans may particularly enjoy it.
