Well, i don't think there's much to add, the first two posts listed the most important (and greatest) bands of the genre.
The NEW RELIGION E.P. that has already been mentioned is great indeed, some of the finest QUEENRYCHE-like power metal i've ever heard. Arkeyn Steel must rerelease it one day!
HELSTAR's "A distant thunder" and "Nosferatu" probably fit the bill as well.
SLAUTER XSTROYES are the ultimate gods for sure...
Also FINAL ASSAULT from Corpus Christi, Texas have some prog songstructures in their otherwise crushing epic power metal style.
No matter how strange it may sound, the debut album of DREAM THEATER and the MAJESTY material are extremely awesome prog/power, still metal and without any weird influences.
LONGINGS PAST are RUSH-inspired epic metal with strange vocals that some may find annoying, they are worth a shot though.
DELIVERANCE from New York with Sword of the necromancer demo are brilliant, many RUSH elements but very powerful at the same time.
SMOKESCREEN's first demo is great as well, haven't heard the second one yet which is supposed to be even better.
OBLIVION from Florida with their Quest for power demo, crushing stuff for sure.
Also ASSALANT from Texas with their Damage is done demo.
OUTLANDER from California are interesting.
Don't know why SOLAR EAGLE haven't been mentioned yet!
