Name the bands who's music dont fluxuate badily.
Bolt Thrower, the most consistent death metal band to date i dare to say.
Deceased, although they have change genres a few times, they have shown that they are capable of doing so. See reviews on Metal-Archives.
Master, another consistent death metal band, but i got to say Bolt Thrower is more consistent.
Motorhead, one of the longest serving NWOBHM bands and yet still consistent in their work.
King Diamond and Mercyful Fate, its hard to hear when people say his voice suck.
Artillery, one of the few great bands of their country, their sound changed only by alittle from their debut album to their last album. Alittle less agressive.
Throw more in....
Iron Maiden ... Only the the Blaze Bayley era is forgettable
and Death ... Never made a bad album
Same for Atheist
who the hell said King Diamond has a sucky voice! He's one of the reason im hooked to Metal...
Up to 2004, i always think Mayhem was consistent
Hmmm, the band Master, is also quite consistent!
Rammstein.. the german industrial metal band, very constant through out, except the last few which were losing some fire(a bit commercialise) because they wanted to win over the american's listeners, anyway, the unique sound of rammstein is still there
Blind Guardian! how can i forget!
