R.A. Thorburn AKA Crustified Dibbs is a rapper from Strong Island who goes way back to the early 90s and invented that whole stacking thing where you pile lyrics on top of each other like some kind of tough nerd robot having a nervous breakdown. He has worked with pretty much everyone in hip hop and put out three studio albums but he also runs a label and puts out tons of movies. If you're new to his music, I'd suggest you start with "Definition of a Rap Flow* and then "Still Get Through the Day."
