What is the song playing when Kallen is driving towards the convoy holding Suzaku? I've looked everywhere for it for ages, and I can't find it. What's the song in episode 4 of Code Geass (first season) at 12:50, beginning when Kallen is driving towards the convoy? It also plays at 4:35 of episode 11 (also the first season), beginning when Todo speaks to his subordinates.
The song you are looking for is called Outside Road Code Geass. It's the Eight Song in their soundtrack Code Geass: Lelouch of the Rebellion.
