Houdini inspires Stefani

Pop star Gwen Stefani's new album title The Sweet Escape was inspired by Harry Houdini, reports PR-Inside.com.

Stefani appears in her music video for the single "Wind it Up" in a predicament similar to one of Houdini's stunts -- she is shackled to a chain fence as if underwater and struggling to break free.

She explains, "In the video you can see the key coming out of my mouth. When Houdini used to do his tricks, his wife used to pass the key from her mouth to his mouth."

"It's the sweet escape. And I was thinking, the key is the music. It all kind of ties up together."
