I would really appriciate your help. Im looking for it for 2 years
This track is not featured in either of the OSTs, after a long search I found this version:
The Unreleased Album is from people ripping music from the original series and trying to reduce all of the foreground sound be using audio subtraction and splicing from different uses in the series. It's a massive effort and it's a real shame that we'll never get official releases of a lot of Code Geass music, this one for certain really should have gotten one.
