Well Chula loses round one. I don' know any of the others though.

I went blind trying to make sense of the guidelines

Everyone ignore rostasi; he's some sort of vampire who has wandered through time meeting every musician from Orpheus onwards, and he doesn't count. :)

It'll do that to ya.

OK guys I've updated the OP with the current hopefuls. You have 36 hours to disprove any of us.

I'll add more as we get them, and when someone has passed the deadline I'll show them in the OP as being on the leaderboard.

:D ...but I don't know the other three.
...and, to be honest, Lenny White is really well-known.
He's even won a few Grammys for his work thru the years.

Terra Tenebrosa is fantastic and I think fairly acclaimed (at least by metal listeners). Aspid were also a wonderful gem.

As in I lose, or praise be to The Batlord for dropping knowledge you didn't know from the heavens?

I know them and have given a moderate-small amount of listening. It's a gem that might get tossed around here and there by underground thrashholes

Durn.

Well here's Japanese experimental metal/experimental thrash band Doom. Not the punk Doom. The Japanese Doom. Unfortunately they're so obscure this song from their latest album is one of their only songs on Youtube.
