Few people can call the musical genius that is Prince a friend, but Esperanza Spalding is one of the lucky ones. His purpleness invited the 25-year-old to perform during his BET tribute alongside Patti LaBelle, Janelle Monae and Alicia Keys, introducing Spalding to an entirely new audience. Esperanza, whose name means "hope" in Spanish, released her self-titled debut album in 2008, which rose to the top of the Billboard Contemporary Jazz chart and remained there for over one year. Today, the stand-up bass player and composer is releasing her sophomore album "Chamber Music Society." ESSENCE.com spoke with Spalding, who's currently in Finland on tour, about meeting Prince, writing songs about escorts and the meaning of "Chamber Music Society."
