Metallica - Master of Puppets - Downpicked @ 250 BPM - LIVE Guitar Cover

Hey RUclips,
This year is the 35th anniversary of this absolute monster of a record coming out, and this song in particular has always been somewhat of a benchmark/grail of rhythm playing and downpicking technique. Inspired by watching all the old live videos of the guys playing this in the 80's I set out to get through this song at 250bpm - just without any of the cocaine and Jack Daniels (because although I do hate my right hand, I don't hate my liver and nose canal). This is just a two take cover for the rhythms (left and right). I went back in for the solos to get different camera angles, the rest is as live as you can get with one guitarist playing both parts.
Big thanks to my friends Nizar (vocals) and Frantisek (mixing) for helping out with their parts.

What should I downpick next? Necrophagist? Decapitated? the Beatles?!
