Portal 2 Trailer Music

portal-2

What is the music in the Investment Opportunity trailer? I'm not talking about Reconstructing Science, I'm talking about the wake-up sound (the one that also plays during the movement tutorial in the game itself, and is kind of garbled and corrupted at the beginning of "The Wake-Up Call"). It's the music featured in this trailer. I appreciate any help anyone can give to this two-year-old question of mine!

If you mean the music that I think you mean, then it's Santorini, by Greek instrumentalist Yanni Hryssomallis. The original is here.

It sounds like an electronic version rather than the original in the trailer though.
