It plays after the intro cutscene when you follow "Cheryl" into that alleyway. It's not the intense song that plays in the alleyway, but the one that plays before it. It has this echoing feel to it.
I'm posting it here because Media would just redirect me to "undefined".
EDIT: Nvm, I found it. For some reason, the playlist on this wiki did not include the song. It's "Dead End".
