Mythodea — Music for the NASA Mission: 2001 Mars Odyssey is a choral symphony by Greek electronic composer and artist Vangelis. Originally premiered in concert in 1993, it was published in 2001 by Vangelis' new record label Sony Classical, which also set up the NASA connection and promoted a new concert.
The 2001 version of Mythodea was recorded and played on-stage by: Vangelis on synthesizers and keyboards, the London Metropolitan Orchestra augmented by two harpists, sopranos Kathleen Battle and Jessye Norman, the chorus of the Greek National Opera, and, for the concert only, the Seistron and Typana percussion ensembles. The concert was held in Athens, Greece on June 28, 2001, and the record was officially released on October 23, 2001, to coincide with the 2001 Mars Odyssey spacecraft entering the orbit of planet Mars. A video of the concert was released in early 2002. (http://en.wikipedia.org/wiki/Mythodea)
