Iara Lee (“Synthetic Pleasures”) has made her second documentary, about the people who created and developed the broad class of electronic music. What she didn’t make was a film about the people who support the scene. I have no idea for whom she made this film. When you’re at a rave, you tend to be dancing and looking at the pretty lights. You DON’T look at the geeks hunched over their mixing boards. Unfortunately, that’s what you get in this film, a whole bunch of geeks. Lee even lets them ramble on about their favorite equipment, in true “Guitar Magazine” style. It’s ironic that a film about music you stay up all night listening to, just put me to sleep.
