A recurring theme in Wald's work is to identify and confront myths, especially but not exclusively those that have come to surround prominent figures in popular music.
"Myths", Wald remarked in 2002, "are marvelous things, the keys to understanding a culture.
"For forty years, white folks have had this myth about Robert Johnson selling his soul to the Devil, and that says a great deal about white fantasies of blackness and its links to mysterious, sexy, forbidden powers."Back in 1936, black folks in the Delta had a different blues myth. It was that a guy who got good enough on guitar and learned how to play the latest hip sounds could get the hell out of the cotton fields and make enough money to move to Chicago, wear sharp new suits, and drive a Terraplane."
Indeed, his first book was a collaboration with his biologist mother entitled
Exploding the Gene Myth, in which they wrote that "The myth of the all-powerful gene is based on flawed science that discounts the environment in which we and our genes exist." "There are no definitive histories," he would come to write in
How the Beatles Destroyed Rock 'n' Roll (2009) "because the past keeps looking different as the present changes."Elijah Wald,
