Lupe Fiasco considered unplugging his mic back in 2012 in a series of tweets, seemingly written in response to a threat from fellow Chicago rapperChief Keef. "This album will probably be my last," he wrote. He said something similar back in 2007, that he was “85 percent sure” he was retiring "soon." "My whole energy for making hip hop music is slowing down," he said. Four years later, he had his first #1 album, Lasers.
