Mega Man X has the most kickass soundtrack in history. That has never changed and it never will. Sure, there are some that exceed it in terms of emotion, tone, and thematic consistency, but there is not a single soundtrack more BADASS than the one for this game.
BREIS is a really cool cover artist whose main forté seems to be the Mega Man X series. He even remixed the entire soundtrack to MMX2. But this particular song may be his coup de grâce. I can't provide you with a link to his channel or website, because he doesn't have one. Good luck searching for him, I tell ya tracking down all of his stuff is a bitch.
