Immortal

Immortal is one of the biggest influences and some of the greatest pioneers in the Scandinavian BM-scene...

While they are a good band, they're not really pioneers or anything.

Which album did Hellhammer play on? He was a session member wasn't he?

He didn't play on any album. He just helped them out on some tour.
 
How does 'Battles in the North' stack up to 'Pure Holocaust'? I've got PH and love it. I suppose I can't really go wrong with BitN, but I thought I'd ask anyway.
