Well it's a no brainer. Judas priest. Nothing beats a free wheel burning and the best ever live sound on stage IMO. Metallica? Sure. Kill'em all ok, Ride the Lightning excellent, Master of Puppets cool, Justice for what?...

Then It's all a blur of slow BS riffs from there on with the 'occasional wake up call'. Came to my senses and hoped the Mustaine way. That's what a good riff sounds like.
