Julian Casablancas [SEP] Early life
Julian Fernando Casablancas was born in New York City on August 23, 1978, the son of American businessman John Casablancas, who founded Elite Model Management, and Danish former model Jeanette Christiansen, who was crowned the 1965 Miss Denmark. His paternal grandparents were Spanish, with some roots in Catalonia. When Casablancas was eight, his parents divorced. He once stated that he wanted to be closer to his father, which "translated into teenage rebelliousness". His mother later married painter Sam Adoquei, who helped shape Casablancas' early musical taste by exposing him to music such as The Doors, which was markedly different from the mostly Phil Collins-influenced music he listened to as a child.
