So... Pmac. He is from San Francisco and he loves making music, according to his Facebook. I really have no idea what more I can tell you about the guy, perhaps we should interview him? Anyhow, the most important thing is that he seems extremely talented.
I love how Rollie Beats incorporated a sample from Three Dogs Night’s song One which by the way isn't very impressive by itself. However, sped up and combined with the rhymes of Pmac makes an explosive combination!
