Aside from founding and playing in Devo, Casale also shot almost all of their music videos, and according to his Wikipedia page, he...
"has also directed videos for other artists, including A Perfect Circle ("Imagine") Rush ("Superconductor"), the Foo Fighters ("I'll Stick Around"), Soundgarden ("Blow Up the Outside World"), and Silverchair ("Freak" and "Cemetery"), among others."
As a total aside, one of the first links I found when I Googled "Gerald Casale" was this interview with him on a very mid-90s looking site called The Vermont Review.
My talk with Casale will be on Sunday from 3-4pm, venue TBA.
