Only looking at music as math and theory, is like only looking at the love of your life as flesh and bone.

Swinging to the rhythm of the New World Order,
Counting bodies like sheep to the rhythm of the war drums

Expand. Learn some music in genres that you would not normally play (classical, jazz, etc.)

Also, I would strongly recomend checking out some old blues players. A lot of metal and rock players have very strong blues roots. Here are a few names for you:

Robert Johnson
Son House
Howlin Wolf
Charlie Patton
Muddy Waters
B.B King
