Background[]

Karl started out as a drummer before becoming a vocalist. Aged 16, he originally said that he had no interest in pop music and went with indierock and deathmetal types of music. He met Max Martin, a music producer and songwriter, through mutual friend Julius.

Julius kept sending Max indierock/ deathmetal demos by Karl but in 2006, Max invited him to a demo to see what Karl would be like making pop music and since 2007, Karl has been signed with Maratone, Max Martin's production company. His first songs whom he co-wrote with Max Martin were Pink's "So What" and Britney Spear's "If You Seek Amy".
