What's the name of the background music which starts at 37:31 in episode 1 of Fate/stay night UBW (2014)? In episode 1, the music starts at around 37:31 or so according to my timestamps, during the fight between Shirou and Lancer inside the main house, right after Shirou blocks the lance and gets cut, and a second before Lancer says 'Hoh'.

I searched entire OST, but seemed to have missed it anyway.
It's likely to be "Face to Face", the 5th song from the OST.
