What is the song that was playing in Code Geass R2 episode 10 at 11:50? What is the song that was playing at 11:50 in Code Geass: Lelouch of the Rebellion R2 episode 10?
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.
