The entire Rust In Peace album never ceases to blow me away. As its been said, play that album for anyone, and they will too see why they majorly own Metallica. Metallica never got even close to RIP.

Good luck with Hangar 18. Great song, guaranteed difficult. I can play portions of the rhythm parts from Holy Wars, Tornado of Souls, Rust In Peace, and Take No Prisoners, and even they can be tricky. So I can't imagine how the leads are.
