This one is easy its famous the Music video is unique I can't find it because
 

Google algorithm is killing me.(maybe alzhiemers)

I don't remember the artists name or the song name.

But the video is great. I think its mostly a instrumental song. The music is just the greatest build up for a sword Battle.
You had comments saying that they want this song played at their funeral.

So they show a huge guy in an afro wearing something like a Robe and he seems to trying to focus.

The music seems to be building up to a fight.

I am not sure but he even picks up a sword. Or the music was so good that it made me think he was going for a war.

The anti-climax is he enters the building and then he actually reaches an underground illegal fight club.
But it turns out to be a video game fight.
Then he plays a video game with someone and wins.
And then he goes back I guess Not sure> it seems he goes back like a winner.

This guy looks like a very serious Reggie Watts and a well trimmed Afro.

But dressed like a swordsman like a Robe and stuff.

The tune was sick It was mostly some wind instrument a trumpet or a sax or similar.

Thanks.

Nah this is not the one. That song is not a rock/Metal song. Its more of a trumpet but has an electronic edge to it.
It sounds like the japanese movie background music
