I'd recommend
Abre Ojos (funny, I was just thinking of this project today) - dark, modular synthesised drones and sounds with wordless vocals and real-time video imaging.
Also, Robin Fox's
"Backscatter" dvd, using "an old analogue oscillioscope" in time with fucked up electronics. Very good stuff, gets a lot out of a little.
I've had the pleasure of witnessing both these projects live and they are well worth the time. Also agree about the Botborg dvd, gets pretty intense sometimes (my copy stuffed up, unfortunately, so nice to see it on Archive).
