Has anyone heard this piece before?

[•ÇØM]

I downloaded this piece from some forum and forgot if it was either a piece that was composed in the 18th and 19th century or a piece that someone recently composed.

Here's a link if you want to hear the piece: https://www.savefile.com/files/2984562

I was also wondering how you would rate this piece's difficulty.

When I first listened to it I found it hard but maybe i'm not at that level of playing yet.

I used this software to get a better look on how hard this piece was: https://www.vanbasco.com/download.html?product=1

If anyone can identify this piece i'll really appreciate it.

thanks in advance
