Big Sean had a ceiling, it was believed. When the Detroit rapper signed with Kanye West’s G.O.O.D. Music in 2007, it wasn’t because he was some mad visionary like Kanye is. From his ’07 mixtape Finally Famous to the 2011 album of the same name (if not all the way to 2013’s Hall of Fame), Sean had a lock on a charismatic — and sometimes poppy to the point of being soft — rapping style. He seemed aspirational in a money-chasing sense, but not necessarily an artistic one. Maybe it was “Control” that did it: Kendrick Lamar’s instantly legendary verse showed a young artist with an extreme confidence that he was onto something. Getting washed on his own track must have inspired Sean, on some level, to grow as an artist, and he has. He’s outlasted the life expectancy that was predicted for him, learning new tricks along the way.
