Skylar Grey says her video for 'Invisible' was meant to replicate the feelings she had in middle and high school, when she felt like a loner, ignored by her peers.

In behind-the-scenes footage, Grey says, "With this video, I wanted to capture that feeling of loneliness, where, no matter how hard you try or no matter what you're doing, all the people around don't notice."

Grey walks on a construction beam hundreds of feet in the air and sets herself on fire in the video. She explains, "I wanted to do something with this video that was more of a visually stunning piece. I wanted it to be kind of a poetic, Peter Parker by day meets Spiderman at night thing ... An everyday kid who isn't really that cool, but there's something else going on that people don't know about."

Grey says the story mirrors her own path in life. "That's kind of the journey that I went on. I discovered that my insecurities and my flaws were things that I actually needed to embrace, and I let them become my superpowers."

With a Grammy nomination for Song of the Year and songwriting credits for Eminem and Dr. Dre under her belt, Grey is invisible no more. The song appears on Grey's album 'Invinsible,' due later this fall.
