Wired.com has a great piece on how an obscure work of Electronic Music, recorded in a Manhattan apartment with a rudimentary home recording setup, wound up in the movie of the moment, The Hunger Games.
In 1972, Laurie Spiegel recorded a nine-minute piece, “Sediment,” on her Electrocomp 200 analog synthesizer, using just two stereo reel-to-reel decks. Bouncing tracks back and forth, Spiegel played along with the material each time to build up the track, but as she notes, “You piled the tape hiss and noise for every generation you added.”
Home recording was unusual back then, to say the least, but Spiegel recalls an added hurdle:
“It was a five-room apartment running on a single 15-amp fuse,” she said. “When the refrigerator went on, half the oscillators dropped by a quarter tone…. I had to turn the refrigerator off, or it would ruin the take.”
