The Black Keys
Friends since they were kids, Auerbach and Carney both dropped out of college and mowed lawns for a living when they first started their band in 2002. They got the name from a schizophrenic artist in Akron who called the two "the black keys," a phrase he used to describe people who "weren't quite right."
