Vega, Crazy Lixx, HEAT, Degreed (this year will hit 5 winners ), ditto for Eclipse...no 5 this year will no doubt be great (I don't include their first 2 as they certainly hate them and they are never being recognised, played live or 're recorded)
But I agree every band from yesteryear has at one stinker in their history (although I can listen to Hope & VOR they are definitely weaker)
Can't think of any of favorite bands who've released over 5 albums that haven't released at least on bad album.
Danger Danger - Dawn
Dokken - Shadowlife
Dream Theater - The Astonishing....ly fucking brutal release
Van Halen - III and for the most part Diver Down
Harem Scarem - Hope and Voice Of Reason...I honestly can't listen to either
Lillian Axe - pretty much everything after Psycho...
The only band that comes to mind to have released at least 5 albums, that are HH material and none have been poor or bad is likely H.E.A.T. although I've enjoyed some much more than others.
