They used to earn tips delivering pizzas in Austin, but now the four members of Riddlin' Kids are knocking on the front door of the music industry. The Texas punks' 2002 major-label debut, Hurry Up and Wait, featured a peppy mall-core mini-hit about heartache ("I Feel Fine") and a light-speed cover (R.E.M.'s "It's the End of the World as We Know It"). The album hadn't even hit the shelves when the lucky Kids landed a spot on the Warped Tour. In the wake of Wait's release, the group has been road-dogging it continuously, proving that an energetic live show might indeed be the cure for attention-deficit disorder. At least the musical kind.
