Self-proclaimed mash-up God ReLiX The Underdog managed to unearth three legendary verses from three of our favorite artists. “Instruction Manuals” brings together A$AP Ferg, Riff Raff and Action Bronson for what many of us would consider a dream collaboration. Take a listen to the impressive track below and check out ReLiX’s Soundcloud for more dope mash-ups. Look for his latest project Bangers & Mash to drop soon.
