Cheesiest Black/Dark Metal sellout

Easy...

1. The Jeff Mantas E.P. "Winds of Change". Sounds like an album of Survivor doing Rocky theme songs.

2. King Diamond's sidekick Hank Sherman's hair band "Fate". Two pretty good hair albums.

Also gotta mention Celtic Frost Cold Lake (I Love it!); and the band Lucifer's friend, who turned into a boogie/prog band that was obsessed with young girls (they never were metal though).
Dan Swano has done some strange things (usually good); some some people just don't buy the concept of Opeth at all. Also Tony Iommi was drifting this direction in the late 80's; as he featured more and more of the keyboard stylings of Jeff Nichols. But the Mantas E.P. takes the cake IMO. Any others?

I should have mentioned that Mantas was the guitarist in Venom, but I'm sure you all knew that.

Kovenant
Samael

both went the way of the dancy beats
