Yup. I do music too.
This particular arrangement is the first movement of a 5-movement, hour-long arrangement of music from The Legend of Zelda by Nintendo.
The piece will move through every installment in the series (up to A Link Between Worlds), in release date order. The first movement, "A Legend's Dawn", goes through the first 4 games, and introduces Ocarina of Time (the fifth game), which will be the beginning for the second movement.
I'll just have the link down below; I don't trust uploading the file to work.
