GRAVE DIGGER. How badass of a band name is that? They even have a self titled song that is one of their top hits, (The Grave Digger), they are a late 80's, early 90's German Power Metal band, famous for intense vocals, crazy use of an organ piano in some songs, and melting faces of course. I have EVERY SINGLE CD OF THEIRS. They are THAT good, I highly suggest you go check them out, especially their more recent CDs, as like a fine wine, they seem to better with age, not get worse, like some metal bands we know of... *METALLICA* cough cough***
My absolute favorite song of theirs is The Terrible One . It has a really nice balance between vocals and guitar incosistent with the rest of their songs, most others have a disproportionately high amount of singing with much less emphasis on the instruments. This song is great, but the band's heavy emhpasis on vocals can be a bit tiring at times.
