Alright, its this guys turn to suggest provocations for ear violations.
I might know a thing or 12 about good rock/metal.
First, start off with the classics.
ACDC - Thunderstruck is a great way to get back to the heart of it.
Black Sabbath - Paranoid rocks!
followed by a random jukebox of -
Children of Bodom - Silent Night, Bodom Night
Lamb of God - Nippon ( very rare and very deadly

)
Iron Maiden - The Trooper or Aces High
Judas Priest - Breaking the law or Exciter
Rammestein - Feur Frei
StaticX - Get to the Gone ( is a must)
Drowning Pool - Step Up
DethKlok - Awaken ( for all yall cartoon metal band fans

)
and to top off the list with some grusome death
Six Feet Under - Bonesaw
thats it kids take it in, digest it, puke it up, rinse and repeat!!
_Cheers_
