With a guest appearance by De La Soul and a storyline that's just been optioned by Chris Rock, five MCs have joined forces for the preschool set as The Dino-5. Animated videos are soon to air on Noggin TV, and a nationwide tour is in the works for this summer, but just who are DJ Stegosaurus, Billy Brotosaurus, MC T-Rex, Tracy Triceratops, and TEO Pterodactal? Put away your pick and shovel: This prehistoric crew is none other than Prince Paul, Wordsworth, the Jurassic 5's Chali Tuna, Digable Planets' Lady Bug Mecca, and The Roots' Scratch, respectively, as the colorful young dinosaurs. The Baby Loves Music Records label is releasing the self-titled CD in early April, narrated by spoken-word artist Ursula Rucker.
