Help is needed here!!!!

Nevermore, i thnk they are power metal. I love the vocalist and the guitar riffs are so low because of the 7 string guitar. It really kicks ass. I reccommend Dreaming Neon Black or Dead Heart in a Dead World.
 
I dunno about that..I'd call it Groove-thrash, or something..with a few doses of American power influence. There are better bands in that type of thing though IMO, but just the same, maybe he would dig them..

I would have also mentioned Crimson Glory and Fifth Angel but they aren't straight power either.
 
Yea, but nevermore is pretty heavy, but i didnt know if they were on the line or not. Hey, he might like it though, they are a really good band.
