Frick, this is a tough call. I've decided to go with relatively unknown and older US bands.
Kalaban - If you don't mind me running over, Procyon's Demise at 10:02 is an awesome choice. Shorter, Greysleyer at 2:36 kicks butt.
Fireballet - Carrolon is a great choice
Mirthrandir - Number Six is good
Crucible - Over The Falls
Ozone Quartet- Mutoid Man
I got lots more if you end up short on time
