As I said in the Skype group, this intro is beautiful. The shifting from the left to right speakers (which is called panning, for the rest of us) works pretty well, and it definitely gets you hooked for something. I can't wait to hear that "something".
By the way, if you're gonna advertise our "collab" to YouTube, don't just say "we have a collab". Explain what it is in detail. It almost seems like you think everyone knows about BA and our collab. Well, there are about 7 billion people in this world, and only about 50 of them know about us.
