Before the 2013 Slam Dunk Contest kicked off on NBA All-Star Saturday Night, Fall Out Boy reunited for their first television performance in over three years. Lead by member Pete Wentz, the pop-rock band performed their new single “My Songs Know What You Did in the Dark (Light Em Up)” at Houston’s Toyota Center on Saturday night. The surprise during their set came from 2 Chainz, who debuted a new verse on the song. The ATLien plays a lead role in the song’s video that released earlier this month.
