There are some solos that get overlooked because they're on an album with so many other great solos. I think think this is definitely the case being that Leper Messiah is on one of what I consider to be the top five metal albums of all time, Master of Puppets. This solo is tricky in that it has a deceptively difficult sweep picking pattern that is not technically demanding, but rather tests your time and technique. Sweep picking is much easier to do super fast or super slow, but mid-tempo I find is the most challenging. This solo is full of Kirk Hammett staples, from hyper-speed descending single-single string runs to over-the-top bends and a healthy dose of wah-wah.
