Have you worked on any pieces of music for specific alien races?

I did at some point, but more recently we've been focusing on landing zones and planets and places where we can explore. Why? Because that's what I've been requested to do. That's the most basic answer. But also because the more defining pieces are where you are. So far, the planets I've scored are planets where there's still no trace of alien races, at least as far as I know.
