The first cover features the artist Shepard Fairey’s illustration of Paul McCartney and John Lennon. “The Power of Two,” by Joshua Wolf Shenk, uses these giants of music to demolish the myth of the lone genius, and as a case study that demonstrates how the creative friction between two disparate, even clashing personalities can yield remarkable results. To illustrate this, I wanted something iconic—and who better to create an iconic image than the skate kid who went from dodging the cops to (arguably) helping a president get elected to being an icon himself? I have a feeling that this rendering of the two Beatles will, like their music, endure for a long time.
