"Majestic Ape, a.k.a Amanda Kleinman, elaborated: "The idea for the project was initiated by David KatzNelson after I mailed him a bunch of pen and ink portraits and a picture book that I had shown in a gallery in DC over the summer. I didn't go to art school but I've been making comics, portraits, books, and big weird 3D critters for some time. I started doing portraits because there are so many crazy and awesome looking people in the world and I wanted a chance to keep a collection of their images. When I play rock music, I'm basically bombarding a listener with my sounds. When I draw pictures of people, I'm getting something from them and giving something back."

Please stop trying to confuse this issue. She admits to using a voice changer in one of the videos and you can also hear her real voice underneath at one of the shows. She is also on the Apes website and has been doing this characteur since at least 2004.
