Shiny Toy Guns! I mean, its the furthest thing away from metal, but you asked for something fresh right? I'm in your boat too, i keep lurking on profiles and checking out stuff i've never heard of.
Definitely; Battles and Pure Reason Revolution, awesome bands. Also listen to Muse, Origin of Symmetry and Absolution especially, they rock socks, Matt Bellamy is truly one of the great guitarists of our time...
I like Dustin Kensrue a lot. His album Please Come Home was really good. At the very least, it's a change of pace. Check it out. My favorite songs are "Pistol," "I knew you before," and "Blood and Wine."
