"Under The Influence//Random+Null Objects//Filler-Arc," a mysterious video game hip hop music video

I received a link to this Youtube video via the site's contact form with the message, "Rgua Ua Die Tiy".  Then the track cuts off as abruptly as it came into my life...

I've got to get some feedback from the hip hop heads, but all my diligence by way of Google have yielded no further info besides the info-less Youtube page of Kelechi Amahk, who uploaded the video on March 12, 2015 alongside several others .
