Yes, to my knowledge I think this is the first auditory appearance of Gus, should have been more clear on that. I should have said "I would like to hear more from Gus." Sorry about that.
@@green_creeper288 Huh, I did post an answer but it seems to have disappeared... I presume a spam filter ate it. So I'll answer without giving any links to anything... Wayback Machine managed to capture the description to that "scary music" video, including the content-id block, so it looks like the song was mixed from two tracks: Redhooknoodles - Hard Scary hip-hop beat Part 2 {Rap} Instrumental Ahmato Beatz - Hard Hip Hop Rap Beat in FL Studio 8 The first one is the more recognisable one in the QWRPLine clip.
