Anthrax guitarist Scott Ian spoke in an interview with Noisey and explained his thoughts on Master Of Puppets album with an extraordinary description. He said:
“You have to remember that this was 1986 and they were breaking new ground. When I listen to a song like ‘Master’ or ‘Sanitarium’ now with 30 years of experience, it’s easy to see what they did. But in 1986 it was E=MC2.
“It was unfathomable. And I haven’t even gotten to their masterpiece ‘Orion’ yet. Seriously, did they find a bottle of Beethoven pills?! How did they have the maturity to write an 8-and-a-half-minute instrumental that works?!
‘Orion’ is moving, it’s cohesive and exciting, and it is dynamic. My ears never even had a chance to get bored because Metallica made me wonder what was coming next.“
E = mc^2, equation in Einstein’s theory of special relativity that expresses the equivalence of mass and energy.
