Yo Gabba Gabba!, "Nick Jr.'s new live-action music series", premiers August 20th with Elijah Wood as guest stars.
The Roots' beatboxer Rahzel will appear at some point in the season but Biz Markie gets the hookup with Biz's Beat of the Day:
The first season of Yo Gabba Gabba! will feature a recurring role by Hip Hop legend Biz Markie in a "Biz's Beat of the Day" segment where he teaches preschoolers how to beat-box, and a recurring role by singer, illustrator and composer Mark Mothersbaugh (Devo) in a "Mark's Magic Pictures" drawing segment. Additional guest stars include, Elijah Wood in the premiere episode ("Eat"), Mya, The Shins, Sugarland, Rahzel, Tony Hawk, Laila Ali, Sean Kingston, Nikki Flores, Hector Jimenez, Smoosh, The Aquabats, The Aggrolites and Cornelius.
It's good to see Biz in on this and I think beatboxing is a great way to introduce kids to the rhythmic magic of hip hop.
