U2 fans that turned out for the band's performance in London last night got a little something extra for the price of their ticket: a surprise appearance from Patti Smith.
It was a meeting of the musical minds at Book Expo America yesterday (June 6) in New York City. A sold-out crowd of approximately 1,100 people were fortunate enough to watch punk-rock icon Patti Smith interview legendary rocker Neil Young. The duo engaged in an in-depth discussion about music and the impact that technology has had upon making music.
