Band: Unleashed Power

The only apt comparison I can think of is Manifest Destiny, which is even more obscure than Unleashed Power. Basically, it's a combination of power and thrash metal with gruff vocals. Think Sanctuary meets Machine Head and you're getting close. Of note, they temporarily had one of the more well-known European power metal drummers Jorg Michael among their ranks. He has since moved on and I have no idea if a replacement was ever found or if the band is even still together.
