"How come I've never heard of this before?"
The YouTube channel Lost In Vegas released a video reacting to Metallica's classic "Master Of Puppets".
Created by two Americans, the channel features an initial critical reaction to music they are unfamiliar with.
The duo had released a video commenting on Megadeth's "Holy Wars... The Punishment Due," which ended up being shared by David Ellefson himself.
