Ebba Tove Elsa Nilsson, known as Tove Lo, is a Swedish singer and songwriter who has been dubbed "Sweden's Darkest Pop Export" by Rolling Stone. She is known for her raw pop style, influenced by the grunge style. Its authentic, complex and autobiographical content has earned it the nickname "Sweden's saddest girl". Raised in the Djursholm district of Danderyd, Lo was a former student of the Rytmus Musikergymnasiet school of music. She formed the rock band Tremblebee in 2006. After its disbandment, Lo pursued a career as a writer and secured a publishing contract with Warner / Chappell Music in 2011.
