Twitter: @calscruby, @chrisbrown We've been keeping tabs on Cincinnati rapper Cal Scruby for awhile now. He's no stranger to working with Chris Brown and other high profile artists. He previously released a video with Chris called "Ain't Shit Changed." This time around, Cal is recruited for the feature as he spits both verses and Chris handles the hook. "Welcome To My Life" serves as the title track to Chris Brown's new documentary which is out today.
