Helloween has more than two 'good' albums (Walls of Jericho, Keepers 1 AND Keepers 2, Better Than Raw, The Dark Ride and Keeper Legacy can all fall under "good") Also Keepers 1 and 2 to this day have no peers as far as AMAZING albums go.
Helloween as a whole: HIGHLY influential. Why do you think all power metal singers (including Timo Kotipelto from Stratovarius) sing like castrated boys from Vienna? the melodies harmonies found in Edguy, Hammerfall, Pagan's Mind, Sonata Arctica, etc.... Helloween CREATED power metal and Stratovarius helped heavily to shape it.
Kiske is NOT overrated, he had a short career, which is different, but that guy can out sing ANYBODY in Metal. The guy has range, power and and actual studied voice. What other Metal singer actually has vibrato? He can actually SING, not just scream.
Just because Hansi layers his vocals over and over, doesn't make him a better singer. He's really good, top 5 no doubt, but I'd put him in with Bruce as far as singing talent goes.
It's official, you're on crack
I know taste vary and all that tolerant PC bullshit, but seriously, how can you call Eagly Fly Free's singing "poor?" Name one song/singer that can even match the last minute of that song.
It is obvious that you are just a Kai fanboy and there is nothing wrong with that (I like Wietkath myself), but to not be able to recognize the other members contributions is rather narrow minded. Yes I said it.
