https://youtu.be/Q21DmLCluhs this is a video I took of someone playing this song and I really want to know what it is so I can learn it.
This is Ludovico Einaudi - Divenire, the quoted part starts around 2:00.
A friend of mine plays this song. The original is much faster than the recording you supplied.
I'm quite certain it's Rob Costlow.
Here is a playlist with the song I think it might be.
They all sound pretty much the same so I suggesting checking the others as well in case.
Here is another playlist of the same with another match.
