How we created the Wailing Stone sound effects for “The Message”!
For the Steven Universe episode “The Message”, creator Rebecca Sugar and sound editor Tony Orozco had to create some cool effects for the wailing stone.
Rebecca is playing on a modified Omnichord and Tony is jamming on effect pedals.
In the final version, you can hear a voice singing right before the car battery explodes. That was Rebecca singing!
