Oh whoops, I thought it was a universal list. Didn't mean to insult your personal list.

I'm sorry. I thought Elvis presley was very influential though I don't really like him.
In my mind my list would be:
U.K
Dragonforce
Led Zeppelin
The Specials
Black Sabbath
Bad Manners
USA
Jimi Hendrix
Nine Inch Nails
The Pixies
