Defying Gravity: The Audio Wizardry of Wicked's Live Vocals
19/11/2025 | 32min
In movie musicals, the vocals are almost never recorded live on-set. Instead, the actors pre-record their songs, then lip sync to those recordings while filming. But on Wicked, they threw out the rulebook, and recorded all of the lead vocals live. In this episode, Production Sound Mixer Simon Hayes reveals how they pulled off this audio feat. From cleverly disguised lav mics and in-ear monitors, to “silent wind” machines, to a jaw-dropping live performance of “Defying Gravity,” this is the story behind a truly magical production.
