Kenneth Anger rocks the theremin in this performance of his band Technicolor Skull at the 40th anniversary bash for the Anthology Film Archives held on May 19 in NYC. The band is actually just Anger and fellow occult filmmaker Brian Butler, who perform in front of a giant screen showing clips — some seeming to be remixed or rejiggered somehow — from various Anger films, such as Lucifer Rising and other sources.

It’s not known if any devils were actually raised at this performance, but the roof certainly was! (Sorry, that’s a lame attempt at some occult humor.)

The event was also a fundraiser for the Anthology to raise funds for a project to digitize over 70,000 rare film titles in its library before they completely disintegrate.

It’s interesting to watch this performance as Anger’s playing of the theremin appears to be somewhat random, except he keeps looking back at the screen, as if to see at which point the film is at in order to synchronize the music. It’s a video to watch a few times to see how the music and the images are fitting together.
