Although Rocko is a big deal (and you ain't even know it) he remains slept-on outside of his 2007 smash "Umma Do Me." He's continued to release solid music since that time (including a great single with an unforgiveable Rick Ross verse), but he's probably been most successful behind the scenes; in fact, Future is one of his artists, and has been since 2010.
T-Pain has spoken out a number of times about Future, including an Instagram post that he later deleted. When he implied that Future didn't know how to properly use autotune in an interview with Hot 93.7, it made some ripples.
Rocko was perturbed. In an interview with Vlad.TV, Rocko said: "I feel like T-Pain was out of line. I don't know what was going on with T-Pain. I was actually a fan of T-Pain until he said that about my brother." Watch the rest of the interview above.
