There’s nothing like being able to say “I Told You So” to your haters. Just ask Jamieson, who celebrates his successes to date and scoffs at all who have doubted him on a freshly-leaked cut off his next EP. Singer Shareen Amour guests, joining the London-born, N.Y.-based rapper over Vintage‘s brassy sample work. I Came, I Saw Vol. 3, the final entry in Jamieson’s mixtape trilogy, is scheduled for release in March. In the meantime, fans can still stream and download Vol. 1 for free in the Booth.
