Vangelis’ Prelude from the “Voices” album released in 1995.
Check out my other Vangelis covers! http://www.youtube.com/playlist?list=PL50FBCEEB5B9CC86C
The instrument is a Nord Stage 2 using a sampled Steinway Model D grand piano, sampled Mellotron flute, and some virtual analog synth. Lot of reverb with a hint of echo.
