Somehow I got on this topic with a friend/now coworker of mine today, and he found this site.

This guy's a friend of his...and being a really small world, I just found out he's also a good friend with a childhood friend of mine.
Anyway, he's really talented and you should check it out.
"MC Squared has had the true honor of performing with one of his heroes, Doug E. Fresh, a few times, including at a Nets Game in the Continental Arena with Rob Base and Slick Rick. He is also very proud to have performed with fellow beatboxers of mind-boggling talent who are driving the pulse of the art, including: Afra, Taylor McFerrin, Kid Lucky, Kenny Muhammad, Matisyahu, and many otheres."
