tracks, 1,2,4,5,7,10 for osi, but I really recommend the whole cd. The best way to appreciate OSI is in a set of really good headphones with the lights off, chillin style. Otherwise, only the obvious top layer of the mix will come out, and you will miss the best stuff, like the light effects kevin uses on his voice.
The thing about OSI and why they are called Office of Strategic Influence is that they are basiscally saying they can control your mind through their music. Kevin Moore even says he doesn't want to be labeled prog, but "martial music" because he says he puts forth same level of efforts to maximize his discipline as found in black belts of a martial art. he knows everything...... about music anyway.
Chroma Key is definately chilling music, not metal, but more like Pink Floyd.
btw, kevin calls himself a sound designer, even though he can play better than bach ever could.
