Since its launch in 2007, KidRockers has spanned through 4 cities, providing a platform where families could be exposed to original indie music in an all-ages setting. And since then it has managed to bring in big name acts like Silversun Pickups, Datarock, Nada Surf, and locals like Bleeding Rainbow and The Spinto Band. And now Ape School is set to join that list of storied artists as multi-instrumentalist Michael Johnson carries on the series tradition of providing old music heads and new music heads some much-needed bonding time.
