Can someone suggest some bands with guitar harmonies?

I'm in the mood to have orgasms over multiple notes being played on top of each other
Iron Maiden my friend!

Iron Maiden to Virtual XI = 2 guitarists
from Brave New World to A Matter of Life and Death = 3 guitarists

that's a lot of guitar harmonies
