Look up Saben De Mi (Chosen Few) by Reychesta Secret Weapon featuring Twista and in the middle of the track this guy spits fire faster than you can imagine. If Tech is looking for an insanely fast rapper to jump in on a world wide choppers track or something, this guy would be legit and more than able to deliver (this has to be the fastest lyric spitting ever, even if it is in Spanish lol).
