Moon Unit Zappa (New York, September 28, 1967) is Zappa's oldest child and daughter. She is active as a singer, actress, writer and director.
Contribution to FZ's works
As a 14-year old she contributed vocals to "Valley Girl" (she was credited for her improvised monologue) from "Ship Arriving Too Late To Save A Drowning Witch" - the title was Moon's description of the image on the cover.
Moon was also a guest vocalist on the albums "You Are What You Is”, "Them Or Us" (on the track "Ya Hozna") and on "Frank Zappa Meets The Mothers Of Prevention". Appeared vocally on seven tracks of "Civilization Phaze III".
Moon also appeared in Dweezil's video "My Guitar Wants To Kill Your Mama".
Moon, Kyle Richard and Lala Sloatman appeared in a failed pilot for a show ("Bunny Bunny Bunny") that FZ described in "Video From Hell" as "an Ionesco sort of post-punk sitcom".
Nicolas Slonimsky named his cat "Grody To The Max", based on a quote from Moon's lyrics to "Valley Girl".
