About this episode
Sound is a crucial part of what makes Disney parks feel magical… and it all starts inside the closely-guarded rooms of Walt Disney Imagineering. In this episode, Imagineers John Dennis and Greg Lhotka break down how they use music and audio to bring attractions to life, from speaker systems hidden in rock work, to the intricate timing of a Frozen water ride. Then, they reveal the surprising story of how one of Disney’s most iconic songs got a brand new verse, more than half a century after its debut.
