Introducing himself to his YouTube visitors with, “My name is Rob and I play guitar for the internet,” Rob Scallon shows he is more reserved in his writing than in his playing, shredding metal guitar riffs, usually on unexpected instruments like the banjo, harp, and shovel—no, really! If it has strings on it, Rob will play it, displaying his mastery of fast riffs by covering songs like Metallica’s “Master of Puppets” and Rage Against the Machine’s “Killing In the Name” for his 750K+ subscribers. One of his most popular videos shows the song “One” by Metallica played on one 8-string guitar, except with 5 hands doing the work. With over 115M channel views, Rob Scallon is a monster metal machine.
