Early yesterday morning, T.I. was released from the Atlanta halfway house where he’d been incarcerated since the Luxury Bus Incident of August 2011. To recap: T.I. got out of jail and promptly hopped onto a party bus (while also maybe filming a reality show?), in violation of his parole. A mere 36 hours into his official freedom, he’s already dropped a single — the mega-Southern “I’m Flexin,” featuring and produced by Mississippi rapper Big K.R.I.T. (XXL notes that T.I. was allowed to record in the halfway house, so that’s how that happened so fast.) Given the rapid post-release turnaround, you might expect “I’m Flexin” to contain some lessons from the inside, maybe some reflections on the legal system, or at least some details on the party bus. What does T.I. have to say? In a line: “Prison ain’t changed shit, homeboy.” Okay, then! Welcome back, T.I.; stay away from the oversize, liquor-serving vehicles for a while.
