On October 24, 2010 (United Nations Day), pianist Teresa McCollough premiered Steve Heitzeg’s World Piece — an ecoscore in 192 movements for each of the 192 member states of the United Nations — in a series of performances released on YouTube.

Heitzeg composed World Piece for the San Francisco-based McCollough in 2007 — carefully illustrating as well as composing each movement. Over the next three years, McCollough recorded the 192 movements in multiple sessions, and listeners can now peruse a digital copy of the ecoscore online, selecting a movement/member state to hear each performance. The experience is a gallery of sound and a musical journey around the world — available at the listener’s pace.
