What's the chances that the Central Intelligence Agency recruited musicians in the 1960s to help spread their propaganda campaign? When the CIA was finished with them they were killed off? Or maybe the influence of the musicians got out of hand and became a threat?
Janis Joplin, Jim Morrison, Jimi Hendrix, Brian Jones, John Lennon and others were all murdered.
