(Update 21st Sept 2010: I replaced the previous video dated Sept 18th 2010, with this newer fixed version which now correctly displays the energy consumption data in Ableton Live)
Video shows a musical composition created in Ableton Live, which responds directly to people's real-time energy usage at various locations across the globe.
Each instrument (1-12) is responding to real-time energy consumption, using data gathered from pachube.com.
If the energy usage at each location is low, the music plays in harmony. However, if the energy usage rises in any of the locations, the corresponding instrument plays discordant sequences which are inharmonious to the composition as a whole.
Below is a list of the instruments and the corresponding location of the realtime energy data received from Pachube.
1) Piano (Aveiro, Portugal)
2) Harp (York, UK)
3) Pizzicato (London, UK)
4) Strings (Petone, New Zealand)
5) Flute (Texas, United States)
6) Gong (Valinhos, Brazil)
7) Music Box (My home energy usage, Cardiff, UK)
8) Nyatiti (Vienna, Austria)
9) Fiddle/Violin (Melbourne, Australia)
10) Rhodes (Chevilly, Switzerland)
11) Drums (Beerse, Belgium)
12) Viola (Muizenberg, South Africa)
For the first 3:30mins i'm interacting with the various musical parts, playing the various musical sequences i created.
At 3:30mins, i begin receiving the data from Pachube and the composition plays dependent on the real-time data from the various locations around the world.
At 7:12mins, i stop receiving the data and continue interacting with the musical sequences myself, once again showing the various harmonious/discordant elements.
Note: The 'music box' instrument is playing sequences dependent on my own home energy usage, gathered using a 'current cost meter'.
At 5:23mins, i boil a kettle of water and this interacts with the composition, by making my energy consumption jump from 109 Watts, to 1980 Watts. (You see the musical sequence for the 'Music box' (track 7 in Ableton Live) change accordingly.
Each musical sequence in Ableton corresponds to the data received from Pachube. The top sequence will play if the real-time energy usage is between 0-99 watts. (Harmonius)
If the real-time energy usage rises to between 100-199 watts then the next sequence below will play.
This continues until the lowest sequence which will trigger if the energy usage is between 2,000-10,000 watts (Discordant).

(I'm currently using an arduino, processing, max/msp, ableton live and a current cost meter monitoring my home energy levels)
