Freddie Gibbs wasn’t supposed to make it this far. A decade ago, Gibbs was a major-label refugee who’d returned to his roots as a Midwest mixtape rapper. When Gibbs found critical acclaim, when he reached the point where he could perform on a festival stage in the middle of the afternoon, that felt like a triumph. But Gibbs just kept making good decisions and rapping at an extremely high level, and he’s now known as one of the most consistently inspired rappers on today’s landscape. Gibbs’ performance on last night’s Tonight Show should show you the kind of respect that he commands.
