Underrated Metal Bands

Inspired by the most underrated band of all time thread.
Most underrated "of all time" is obviously a matter of opinion so I'm just talking in general about metal bands who probably didn't get their just due.
I'll throw out one damn good one and then two of my favorites.

Alabama Thunderpussy -- R.R.C.C.
I saw Corrosion of Conformity at Jacksonville Beach in '05 with Crowbar opening. Well, before Crowbar played these guys got up onstage and absolutely crushed it. I became a fan immediately. Just good, dirty, grungy, southern metal. They fit the definition of underrated perfectly because I saw them again a couple of years later headlining and there were literally about 25 people there. Pretty depressing. They've since broken up without ever getting even close to the recognition they deserved, IMO.

Accept -- Fast as a Shark
One of my alltime favorites. They came out of Germany and were absolutely shredding some GREAT heavy metal in the late 70's and early 80's. I was lucky enough to see them twice on the Balls to the Wall tour, opening for BOC at the Saenger in New Orleans in March of '84 and then again in June '84 opening for Ozzy in Biloxi. Their show as a headliner though at the Saenger in August of '85 still rates as one of the greatest concerts I've ever seen. Absolutely incredible live. They've made a decent comeback in the last couple of years with a new singer named Mark Tornillo who sounds quite a bit like Udo but with better range. They'll never quite get as much credit as they probably deserve though.

Exodus -- War is My Shepherd

Damn shame that they don't come even close to the credit that "The Big Four" receive. They started the thrash genre right along with the others, coming out of San Francisco same time as Metallica. I'm sure most metal fans know this but Kirk Hammett was a member of Exodus up until being approached by Metallica. Just like Slayer, they've continued to put out really heavy stuff and IMO their musical peak didn't even come until post 2000 with Tempo of the Damned, followed by some more great releases.

Exodus -- The Atrocity Exhibition
This one is long but the three minutes from the 3:30 mark to the 6:30 mark are about as good as metal can possibly get.
They'll always be overshadowed by the other four though.

Anyway. Feel free to pitch in any metal fans.
