I don't believe that's actually Metallica. The drumming is so awful, it can't be Metallica. Why would Metallica ever record something on a POS recorder in the first place? MOP production was over the top, "it took us a week to just bring the equipment into the studio for Master of Puppets" was a quote from the Garage Days interview. That is not Metallica IMO. Unless that is a ton of "wow and flutter" stuff that happens to audio tape, who ever is drumming can't keep a beat. Coming off the 4 going into the 1 after a roll is way bad news for this drummer, even Lars could never have been that bad, listen to it. I just listened again, there's no way that's Metallica, no way, not close, I'll bet you a Les Paul that isn't Metallica.
