Three Acts and Still Nothing?!
This one deserves a lot more attention than it's getting. As I stated on act 3, the whole set is good, but this one is exceptional! I've bee using it as my background music while I'm on the computer for about a week now, skipping about the portal but always coming back here. It's an amazing song and continues to be one of my favorites in your library and for that matter the entire Portal.
Please contact me if you would like to use this in a project. We can discuss the details.
