iPhone/Guitar rapper mixes gimmick with heart

(CBS News) It's a simple equation: "Beatbox + iPhone + Guitar + Fast Rap = Win!" Musician Mac Lethal only needs three tools (his phone, his guitar, his voice) to craft this impressive song about living in the world today. But it's more than just a gimmick; there is real heart in these lyrics. Take a listen.

This guy has got chops. There is some heavy stuff in there between the impressive looping and gadgetry. All opinions are personal, and Mac is certainly not afraid to let his known, so we won't get into that. Except to say one thing: don't text and drive, guys.
