Raiyn, looks like you're new to PW, so welcome!!
If you aren't familiar with Michael Nyman's music from the movie The Piano, here are two videos: The Heart Asks Pleasure First The Sacrife
They're basically the same, except the Sacrifice is slower and is basically just the main theme (and if you see the score, the Sacrifice is less demanding in terms of the LH part).
Anyway, as Rada said, the video you posted does sound a lot of Nyman's music, someone who knows more about chords can talk about why that is, but you should be able to figure out what's being played in the Roland video just by looking at the hands. Or, you could find the score for the Nyman pieces I linked and play one of those, since they are more complete pieces of music. (both should be available through SheetMusicPlus.com or SheetMusicDirect)
