Black Cards was formed in March 2010 by Pete Wentz. Fall Out Boy went on hiatus in late 2009, with Wentz announcing his desire to take a break from music and concentrate more on being with his wife and child. However, Wentz eventually ventured into another musical project, this time experimenting a lot more going to a more electronic dance-ska direction with the music.
Wentz had said he was taking time off with his family, when he started being inspired again by such Jamaican reggae songs as Culture's "Two Sevens Clash" and The Gladiators's "Warriors". Wentz then contacted producer Sam Hollander (Gym Class Heroes, Cobra Starship, Hey Monday) and discussed the idea with him to mash up ska, dance and reggae with 80s British rock and pop to create a new experimental sound. Wentz did not want to attempt to replace Patrick Stump (his bandmate in Fall Out Boy), and decided to go in a new direction taking a female vocalist instead – amateur singer Bebe Rexha.
